iAudio5 strange problem with SuSE linux

[Jose Luis Diaz]

Hello,

I use several computers, some have Windows, some Linux (even with different distributions and versions). I have experience with pluggable USB media storage (I have a card reader, a digital camera and a thumb drive, and never experienced any problem with them).

Now, when I plug my new iAudio5, I get an strange problem. The kernel detects the new device, but complains about "no disk inserted". If I try to manually mount the new drive, the command hangs. If I try to fdisk the new device, the command also hangs. Here is a dump of my /var/log/messages:

Apparently, the drive is correctly detected. However, the device /dev/sde does not respond, and the partition /dev/sde1 is not accesible. When I try to manually mount it (mount /dev/sde1 /media/iaudio), the following messages appear in the log:

Jan 21 21:42:35 kernel: usb 2-1.4: control timeout on ep0out
Jan 21 21:42:36 kernel: usb 2-1.4: device not accepting address 26, error -71

As I said above, I have no problem with other USB drives, so apparently it is not a problem with my linux distribution (SuSE 9.2, linux kernel 2.6.8). However, I restarted the machine with Knoppix, and in this case the iAudio5 automounted without problem, so it appears to be a problem with my linux, after all. I know that my SuSE is a bit obsolete, but I succesfully mounted the iAudio5 in other older linux distros (for example, a Mandrake with a kernel version 2.4.8).

Anyone has a clue about what is happening? Can somebody give me any direction about where to ask?

PS: The firmware version of the iAudio was 1.20.e

UPDATE: I just updated the firmware to the latest version (1.41.e), but the problem persists.

Thank you,
