VT82xxxxx UHCI USB 1.1 Controller (rev 02) Speaker: Typhoon notebook USB speakers (C-Media USB Audio) Specker with an integrated usb-soundcard Software Environment: alsa-lib-1.0.11, alsa-utils-1.0.11, libusb-0.1.12 Problem Description: After pluging in the speakers snd_usb_audio is loaded, and with "speaker-test -t sin" one gets an nice tone. But after a short time (or trying to andjust the volume) the tone stops, and the usb-bus can not longer used. If you need additional infos (parts of the kernel config, etc), just email me. /var/log/messages (2.6.17.8): Aug 12 23:02:20 frodo kernel: usb 1-2: new full speed USB device using uhci_hcd and address 4 Aug 12 23:02:20 frodo kernel: usb 1-2: Product: C-Media USB Audio Aug 12 23:02:20 frodo kernel: usb 1-2: Manufacturer: C-Media INC.
