not detecting prs300

[coolnamehere]

hi -

first, thanks so much for this great software.

I'm using linux, have read the tips about detecting the reader but I'm still not able to send anything to it (just says 'device not found'). I'm using glibc 2.8 so got calibre-0.6.28-x86_64.tar.bz2. another forum post indicated anything newer than ~sept. 2009 should work with prs300 and the rev I grabbed is from dec. 2009.

I used the latest calibre software for xp running as a guest in virtualbox and it worked fine.

now in linux it seems to not be finding it.

when I plug in the reader /var/log/messages says:

kernel: usb 1-2: new high speed USB device using ehci_hcd and address 3
kernel: usb 1-2: configuration #1 chosen from 2 choices

kernel cfg:

% zcat /proc/config.gz | grep SYSFS
# CONFIG_SYSFS_DEPRECATED_V2 is not set
CONFIG_ACPI_SYSFS_POWER=y
CONFIG_SYSFS=y
# CONFIG_SLQB_SYSFS is not set

calibre debug output:

% calibre-debug -d

DeviceError: Unable to detect the PRS505 disk drive. Your kernel is probably exporting a deprecated version of SYSFS.

if I need to supply other info just let me know. incidentally I tried as root and non-root but had the same problem for both.

thank you.

Can you mount your reader in linux?

[coolnamehere]

thanks but sorry, couldn't figure out how to do that

I was doing "ls -lrta /dev" when plugging it in but didn't spot a device for it.

% lsusb
Bus 007 Device 001: ID 1d6b:0001
Bus 005 Device 001: ID 1d6b:0001
Bus 006 Device 002: ID 046d:c517 Logitech, Inc. LX710 Cordless Desktop Laser
Bus 006 Device 001: ID 1d6b:0001
Bus 002 Device 001: ID 1d6b:0002
Bus 001 Device 004: ID 054c:031e Sony Corp.
Bus 001 Device 001: ID 1d6b:0002
Bus 004 Device 001: ID 1d6b:0001
Bus 003 Device 001: ID 1d6b:0001

when I look at /dev/bus/usb/001 there is a 004 but trying to mount just complains it's not a block device (and if it requires a mount parameter I don't know what it would be).

I never added a udev rule - do I need to? iow no device is being created when I plug it in?

[kovidgoyal]

there's something wrong with either your system or the reader if no device node is being created. try it on another computer.

[coolnamehere]

no other computer to try it on.

I found another post saying a scsi device should be getting created for it - looking through my kernel cfg I see "usb mass storage" deselected so that's at a minimum prolly what I'm missing.

thanks for the help, I should be able to get it now.
