Calibre 0.4.56 doesn't recognize Reader

[kovidgoyal]

I dont know, I'm stumped, as far as I can tell calibre should be recognizing the reader, but it isn't.

Basically, all I can suggest is try to clean out all calibre related entries from your registry and your hardisk, then try a reboot/re-install.

But, I think this is one of those cases where nothing short of a full windows re-install will fix it.

Thanks for the suggestion, Bob. It is a desktop but changing USB makes no difference. What makes it so odd is that Sony's software and Windows Explorer recognize the Reader -- just Calibre doesn't.

Thanks, Kovid, for all your time and help. Maybe later I'll run jv16 and weed out all the Calibre registry entries and uninstall - reinstall Calibre and see if it does any good. If not, I can at least use Calibre to convert to LRF and I can then use the Sony software to load the books to my Reader.

If you have the 505 you can just use the Save to Disk feature of calibre to save to the Sony drive. You end up in the same place.

Thanks, Bob. that's what I will do until the Reader gets recognized again.

Kovid, just to let you know: I uninstalled Calibre and cleaned out all Calibre-related entries from the Registry (at least according to Revo Uninstaller), rebooted, and installed the newest release of Calibre. Alas, the problem remains. Maybe someday i will get my Reader recognized again . In the meantime, I'll use Calibre to convert and save to disk, then the Sony software to load the converted file to my Reader.

Again, I appreciate all your help and time.

I thought of another possible point of failure. Once again try running calibre-debug and at the green prompt:

import wmi
from calibre.devices.prs505.driver import PRS505
c = wmi.WMI()
for drive in c.Win32_DiskDrive():
    print str(drive.PNPDeviceID)
    if PRS505.is_device(str(drive.PNPDeviceID)):
        print drive.Partitions
        if drive.Partitions == 0: continue
        partitions = drive.associators("Win32_DiskDriveToDiskPartition")
        print partitions

Kovid, I ran the code and the results are shown in the attachment below. I have installed version 0.4.68 of Calibre. After running the code, I opened Calibre; it now recognizes the Reader. (That's me jumping for joy!)

I don't know what this code did, but whatever it did, I'm now back in business with Calibre. More karma coming your way.

Sorry. I tried to give you more karma but I can't until I spread it around. System won't let me.

Glad it works now

Hi Kovid,

I'm using Calibre 0.4.73 and I have exactly the same symptoms.
I have executed the same diagnostics commands as you previously gave, but I can give you more details.

I'm using Calibre both on my personal laptops and at my office workstations, with Windows XP.
On my personal laptops, I have the administrators permissions and Calibre just runs like a charm.
At work, I have more restricted privileges, and Calibre don't recognize my Sony PRS505.

However, Windows manage to mount my folders, I can access them. I noticed however a weird behaviour of Windows XP at work.
I'm using only one memory card (the memory stick pro one), and the other memory card plug is empty. but windows keeps on mapping it to a hard drive letter.
It might be a clue ?

So, when I executed the diagnostics commands, I clearly saw that 3 drives are recognized, but I have only 2 drives (the internal memory, and the memory stick pro card). Maybe Calibre tries to access the 3rd drive and gets stuck ?

[kovidgoyal]

Hmm, possibly. Try the following

import wmi, pythoncom
pythoncom.CoInitialize()
_wmi = wmi.WMI()
from calibre.devices.scanner import DeviceScanner
scanner = DeviceScanner(_wmi)
scanner.scan()
from calibre.devices import devices
for d in devices():
        if scanner.is_device_connected(d):
            dev = d(log_packets=options.log_packets)

dev.open()
print dev._main_prefix, dev._card_prefix

Is the final line of output showing the wrong drive for card_prefix?

[bodzebod]

I think "options" is not defined.
Here is the error message right after the line containing "options.log_packets" :

---------------------------------------------------------------------------

oops

import wmi, pythoncom
pythoncom.CoInitialize()
_wmi = wmi.WMI()
from calibre.devices.scanner import DeviceScanner
scanner = DeviceScanner(_wmi)
scanner.scan()
from calibre.devices import devices
for d in devices():
        if scanner.is_device_connected(d):
            dev = d()

dev.open()
print dev._main_prefix, dev._card_prefix

Hi!
I have the same problem with my PRS-500... Calibre work ok at home...
but at work, my computer don't recognize the Reader.
The Reader software was ok. (Actually don't see the reader after uninstall the sony drivers)

I executed all the debug code that I found on the thread... these are my results:

So... i see in the 3rd try that the sony reader is connected... but Calibre don't see it....

Thanks in advance!

I have this problem too. (Look at us all come out of the woodwork!) Over the next couple of days I'm going to upgrade to the latest version and then run through the debugging steps here. It hasn't recognized my device since the pre-Calibre days.
