I have an USB-keyboard/-mouse connected to a switchbox which is itself connected to a PowerMac (MacOS) and my PC running Linux. I do regularly switch my USB-devices between Mac and PC. Since I upgraded to kernel 2.4.0 and now 2.4.2 it happens from time to time that Linux does not recognize my keyboard/mouse after switching back to the PC. This leaves me in a rather unconfortable situation, since I can't do anything anymore. All I could do is switch off the power! I tried to disconnect/reconnect my USB-keyboard but it didn't help. My questions: 1. Is there any better way to fix this situation, besides power off or getting a standard keyboard? 2. Is there a minmal time frame of no activity (up to an hour) where any cached data is saved to the disk, so I could switch off the power without corrupting my disk? 3. How can I get more information what's happening? Is there any USB-log/-trace accessable after the restart of linux? And whom/where do I have to send it? O. Wyss PS.
