Linux doesn't see EZ-Reader

WoodLark · 03-23-2010, 08:30 AM

I have an Ez-Reader 6 inch that I just bought. When I plug it in to a USB port on my computer (running Puppy Linux 4.2.1), PMounter does not see either the SD card or the internal memory, so I can't mount them.

I can access the SD card just fine by removing it from the EZ-Reader and using an SD card reader so I can load and re-arrange files on the SD card, but I have no way to get to the internal memory..

Any ideas?

Sorry to reply without being an owner, but I've been struggling with an iliad today with a similar problem. If you get

usb 2-4: device descriptor read/64, error -110
usb 2-4: new full speed USB device using ohci_hcd and address 8
usb 2-4: device not accepting address 8, error -110

Then it looks like it's a kernel problem with the newer 2.6.3x's. I had working for awhile, but after digging around and enough rebooting for half a year I still haven't got a solution. Except for waiting.

Is the unit turned on when you attempt to mount it? (I know...silly question, but I had to ask.)

Did you see the Connect message (And press OK) when you Plugged in the attached USB cable attached to the EZReader?

Be certain the cable is properly seated at the EZReader end.

Dear Woodlark:

Welcome. I work for Astak; but am not a tech. However, I do care to make you happy!

Yes, The Ducks is right! The first thing to do is to check to be sure the USB is seated properly into your EZ Reader 6 inch. That spot on the bottom for the USB is nice as it is out of the way... but it can be a bear to seat the USB cable.

We suggest plugging the USB into the computer first and THEN connecting to the EZ Reader 6 inch. Somehow this works often.

Rarely, the USB cable can be less than optimum. If you have another USB cable lying around, try it please!

You are always welcome to email to: www.support@astak.com or phone:
1-866-368-8788 and talk to a tech!

I'm still not entirely sure what is happening here, but following some of your suggestions, I am able to connect now (although it sometimes disconnects spontaneously). Using a different USB cable and connecting directly to a USB port on the computer instead of through a (powered) USB hub seems to help. Interestingly, when I can't connect, the EZ-Reader goes into the charging mode so there is obviously some physical connection to the computer.

Only charging mode?
Meaning there was only the Battery with a lightning bolt and LED sequence, Not the "Connect: Press OK" or "Connected" Screen.

Direct port is best

USB hubs are notorious for being way under-powered
(each port can be 1/2Amp. 4 ports says the external Power unit must be 2.0A to supply 4 ports fully)

Check for lint in the mini USB port which may allow power contact, but not all the signals.

I just got a brand new Pocket Pro this week. When I plug in the USB cable to connect with my Vista PC, the PC says USB device not recognized.

I tried 2 different Vista PCs, 3 different USB cables and multiple USB ports, and none worked.

Is there any other thing that I can try?

I can think of one thing. The USB port on my PP is the tightest I have had to deal with yet. Make sure the plug is in properly.
