View Full Version : Connecting PE to PC via USB is PITA

I've never really gotten my pocket edge to connect to my main PC via the USB cable. I get two drive letters (J: and K:) but clicking on either one says "Please insert a disk into drive K: (or J:).

When I plug the small USB end into the edge, it doesn't acknowledge it at all -- doesn't prompt to do anything.

Using Windows XP SP3, what SHOULD I see?

I'll try USBDevView (from nirsoft.net) and see if I can wipe off stale USB device profiles, but it seems like this is failing even more than when I got the edge last month.

(updated)
Ok, I wiped a bunch of old USB device profiles, and now the PC "sees" the eDGe, but "The hardware was not installed because the wizard cannot find the necessary software."
I'm pretty sure this is where I gave up after I got my PE!
Where do I get the "software" for the edge?

Any ideas?


Thanks

Drivers? You might look at the device information on the PC to see whether it says drivers are installed and whether they'e the right ones ... and then have it look for newer ones. Just a shot in the dark.

Have you ever tried that on an other PC?

did you click on the button that turns it on on the pe after connnecting?

I find that it is easier to set up a Share folder on my PC and then transfer files wirelessly from the PC to the PE. Use ES File Explorer and in the upper left hand corner touch Local and a pull down menu will appear. Select LAN. Press Menu, Select New, and Scan. The PE will search for PCs within range. If your PC has a static IP address you can select server and enter the information manually and you won't have to scan every time you want to transfer files.

The latest in the effort is that, despite the apparent install failure, I get one drive that works - with documents, download etc at the root, and the other drive remains "Insert disc in drive K:", so it's inaccessible -- no doubt the micro-sd.

I only have two computers and a server, and I get the same response on all three. No "box" pops up on the edge when I plug it into any of them. I have to drag down the bar at the top and enter the USB connection dialog manually.

On all three systems, I get the "new hardware" dialog, and all three see the device as "eDGe", but can't complete the install successfully.

I don't know of anything I've plugged into all three systems that would cause a spoof and keep the eDGe from being recognized, and I rarely plug anything into the server because USB as a technology is inherently flaky and I don't want to pollute that system.

Since one drive works, and the other doesn't, there must be some way of enabling the sd-card as sharable, possibly through Settings.

I found a good deal on a 32GB micro-SD, class 6 yesterday and ordered that and the Startech USB ethernet adapter, so I'd be nice to be able to load data to the SD from a connected PC and not an Android file manager which doesn't have drag and drop. So that's why I'm revisiting this problem.

If the SD Card you have inserted in there now is not formatted correctly Windows probably wont recognize it and may come up with that error...

I've honestly always had 2 drives and only 1 work. I swapped the library onto the SD card and just ignore internal memory. The 1st drive shares /sdcard

Maybe you have some drive letters reserved and don't know it? What do you get if you right-click on drive k:, under "information" (or something like that; I'm working from extremely unreliable memory)

sdcard isn't the micro-sd -- that's extsdcard.

I've tried pulling the micro-sd and reading it with a USB card reader directly in a PC and that works, but I'm not excited about pulling the card often as I'm afraid the socket will wear out (as USB sockets are known to do).

When I get the USB Ethernet adapter, I hope it works and produces a 100Mbps connection, but even then, I've heard that the copy/paste function of Android file managers is flaky. When I copy something large to the edge now, I have to copy, paste, then go back and delete since there is no MOVE command, unless someone knows of a file manager WITH it. Also, even the copy/paste tends to lock up my edge on large files.

The native app "device storage" has a move-option. Works very well.

The move function is built into the edge , place a check-mark in front of the file/files and you will see the move option at the bottom.

SDCard is the sdcard if you move the library to your sdcard through the device storage screen under settings.

Mine wouldn't work at first. It finally worked when I connected to the PC first, then to the PE (I think...), and then I finally got the USB notification coming up on the PE; before then, the PE did nothing when connected and didn't seem to know what was going on.

Thanks, yes I see that in Device Storage, the card is "SD card". When I use ES File Explorer, and go to the root, I see both "extsdcard" and "sdcard" (along with "system" and a number of others). So while the micro-sd is referred to as 'sdcard' in some places, in the file system it is extsdcard.

I thought I read somewhere that the internal memory is just an sdcard -- hope it doesn't pop loose! That would be bad.

I think yugami or someone similar found that the internal memory is an actual chip soldered to the board...

I thought I read somewhere that the internal memory is just an sdcard -- hope it doesn't pop loose! That would be bad.

there are 4 chunks of the 4 gig internal memory (which is a single chip soldered into the main board) that are publicly exposed inside the edge. These add up to about 3.5 gig

ubi:system 329928 168456 161472 51% /system
ubi:userdata 329928 183104 146824 55% /data
ubi:cache 330400 36 325528 0% /cache
ubi:storage 2668352 387296 2276220 15% /intstorage

the remaining storage is probably the boot and restore sections that house the kernel image and the code that knows how to access update.zip on external memory.

One of those "others" you mention is intstorage which is the actual mount point of the internal memory Looking inside that directory you will see it contains a vfat.img file which is the actual filesystem you access when accessing the internal memory. This is mounted via a loopback device to the directory /intsdcard

the directory /sdcard is simply a link to the directory that is the mount point for whatever storage you selected to use. so if you selected SD Card if you did an ls -l on the root directory you would see a listing like so

sdcard -> /mnt/sdcard

It works here (on my EE). The Library is moved to the external SD card, too.

The PC here also gets two different drives. The first one does have the "media" in it. The other one is empty.

Before doing the update to Ermine my EE only exported one drive. Anyone know what may be attached to the second drive? I wonder if there's a way to attach the old "sdcard" from internal memory.

yugami, do you know how to fix a problem with a vfat.img file? I think that's my problem. For some reason my /intsdcard is empty and the /sdcard has all the info. I'm trying to make it a link to the correct file, as it seems that it is the issue. You can read all about it here:

I think Yugami may have sold his/her PE. Posted in October offering it for sale. Still around the forum, though, so if you think they might remember you could send a PM. :)

This is all very hazy so use at your own risk.

Before doing any of this I would recommend using the internal tool to move the Library too and from the external SDCard a couple times to try and force everything back into alignment.

Unfortunately I didn't make any notes on the format of the fstab format used by the edge if this is what is messing up.

You can check to see what is pointing were using the command ls -l from the command line. You want /sdcard to point to where you have your library setup.

If you need to make a new vfat.img this is what I would try from the command line:
vfat.img is just a file that is a hunk of space mounted via loopback (a linux think allowing files to be used as devices) the file is 2.5 gigs large and formated with the vfat file system

making the file:
dd if=/dev/zero of=/intstorage/vfat.img bs=1024 count=2621440

formating the file: mkfs.vfat (using a man page on mkfs.vfat so the busybox might be different)

mkfs.vfat -F 32 /intstorage/vfat.img
