Hi all, there has been many success stories about connecting a usb disk to an iBook G4. Well, in may case it also looks ok, if the device wouldn't disconnect all the time. Here is an excerpt from the syslog

I'm using a self compiled linux 2.6.11-rc4 and a freshly installed debian unstable. There has just been a mouse connected to the usb bus when the disk was plugged in. Anybody any explaination for this odd behaviour? Uwe PS: The same usb disk did work on a pismo with linux 2.6.6. -- MMK GmbH, Universitaetsstr. 11, 58097 Hagen [EMAIL PROTECTED] Tel: +2331 840446 Fax: +2331 843920
