Re: System crashes on USB connection



Hi Christoph,

I have a Sheeva PLUG dev kit with Debian Linux release and the USB port is not able to handle having a second USB device connected simultaineously. I tried connecting a USB hub into the single USB of the Sheeva PLUG and then plugging a hard drive into the hub. The PLUG is able to boot using the USB hard drive but plugging anything else into the USB hub disrupts everything. Debian must not coordinate adding additional USB devices without disrupting the first device, probably changing the existing device's reference point within the OS.

Subject: System crashes on USB connection

Hi everyone,

I installed Debian on a USB flash drive on my QNAP TS-419p+(Kirkwood) inserted into the lowest backside USB port.Everything's been working very smoothly until I tried to connect my printer to the NAS (also via USB). Via SSH the NAS reacted with the same error to every command as soon as the printer was connected:
-bash: /bin/dmesg: Input/output error

Upon manual power off (button on the NAS) and reboot, the system took a very long time to come up and finally booted. Since then, the system boots quickly againbut I don't know how to get my printer working.

Thanks for any suggestions,
Christoph
