This is the output I see when they disconnect and LEDs go out: Jun 25 10:42:52 vdr-tng kernel: hub 4-0:1.0: state 7 ports 6 chg 0000 evt 0006 Jun 25 10:42:52 vdr-tng kernel: ehci_hcd 0000:00:10.3: GetStatus port 1 status 00180b POWER sig=j PEC CSC CONNECT Jun 25 10:42:52 vdr-tng kernel: hub 4-0:1.0: port 1, status 0501, change 0003, 480 Mb/s Jun 25 10:42:52 vdr-tng kernel: usb 4-1: USB disconnect, address 2 Jun 25 10:42:52 vdr-tng kernel: usb 4-1: usb_disable_device nuking all URBs Jun 25 10:42:52 vdr-tng kernel: ehci_hcd 0000:00:10.3: shutdown urb cb1b8860 pipe c0008200 ep1out-bulk At this point, the LEDs are out but all of the device files are still there. Anything that tries to access them hangs nicely... I hate USB...PCI cards tend to just work! Unfortunately, I only have one PCI slot in that system and htat already has a DVB card in it! :( Cheers, Laz
