Hi Scott B. :) [OT: IMO it's easier to follow mails, if we answer under the quotes] A shot in the dark ... The Internet gives the information that the us-144 and us-144mkII do support 2.0 and 1.1. I guess the driver modules are part of usbcore, dunno if there's a module you can unload, but I guess you don't need to unload a driver. $ lsmod | grep usb does show the loaded modules. There's a module snd-usb-us122l.ko if I run $ modprobe -l | grep usb perhaps you need a special driver for your us-144 too. The command 'hwinfo' might help: $ hwinfo --usb $ hwinfo --sound I e.g. get the output 'Driver Activation Cmd: "modprobe snd_ice1712"'for my ICE1712 (Envy24) cards. Perhaps hwinfo can tell you what driver you need to load. Connect the device and run 'hwinfo --sound', on some distros you need to be root to do this. -- Ubuntu-Studio-users mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users
