I would not reboot, but just try to stop and start the usb bus. Eg on Mandrake, edit the /etc/init.d/usb file and make sure that the stop option actually does bring down the usb bus. (In some versions this is commented out). Then do service usb restart. instead of rebooting and see if that helps. This does not solve your problem, but at least restarting the usb bus is much faster than rebooting. > I'm using > Advanced Linux Sound Architecture Driver Version 1.0.2c (Thu Feb 05 15:41:49 2004 > UTC). > Compiled on Feb 21 2004 for kernel 2.6.3-1-686. > > I have an Audiotrak Maya EX7 USB sound device connected via an ABSoft > indigo Mini USB 1.1 hub to a SiS 7001 USB controller on my M747 > motherboard.
