[snip ...] difference i see is that gentoo uses uhci_hcd, while xubuntu uses ohci-pci, not that i know what that means... It means USB-1.1 as defined by AMD (I think). lspci | grep OHCI should show if you need it. i would appreciate any help. here is the result of zcat /proc/config.gz | grep -i usb [snip ...] CONFIG_USB_OHCI_HCD=y CONFIG_USB_OHCI_HCD_PCI=y # CONFIG_USB_OHCI_HCD_PLATFORM is not set Try enabling the last module above and see what you get. -- Regards, Mick signature.asc Description: This is a digitally signed message part.
Re: [gentoo-user] problems with usb audio and midi
thanks for your answer! actually, i just realized that it's working now. unfortunately i don't know what of all the things i've been trying made the difference... $ cat /proc/asound/cards 0 [M2496 ]: ICE1712 - M Audio Audiophile 24/96 M Audio Audiophile 24/96 at 0xec00, irq 16 1 [CODEC ]: USB-Audio - USB Audio CODEC Burr-Brown from TI USB Audio CODEC at usb-:00:1a.1-2, full speed 2 [nanoKONTROL2 ]: USB-Audio - nanoKONTROL2 KORG INC. nanoKONTROL2 at usb-:00:1a.1-1, full speed the usb audio card is working. the midi controllers, on the other hand, although recognized by the system, are not seen by the midi sequencers i tried (rosegarden and qtractor). i'll have to investigate more, because it's the midi controllers what i'm interested in. It means USB-1.1 as defined by AMD (I think). lspci | grep OHCI should show if you need it. mmm... lspci | grep OHCI gives nothing, so i guess i'll disable these modules in the kernel. thanks again, and if anyone knows how i could actually use those midi controllers, i would appreciate any help. lj
