I recently installed a usb 2.0 card, on top of the USB 1.1 integrated to my Tyan Tiger MP motherboard.
When I plug my usb 1.1 epson 1650 scanner on the mobo usb, it gets detected fine.
Here is the output

But when i plug it into the pci card, the scanner is not detected

Using kernel 2.6.5-gentoo-r1 with both ehci and ohci code built-in.
I can't see what's wrong. I don't have any 2.0 peripherals yet, but 1.1 ones should work fine anyway with a 2.0 usb bus.
I tried to modify /etc/sane.d/epson.conf to change the usb device (usb libusb:002:001) but nothing happens. The "funniest" is that even after changing that line, the mobo can still detect the scanner.

pbardet,
Since your USB 2.0 card uses a VIA chipset, if it works with USB 1.1 devices at all, it will need the uhci_hcd root hub driver, not the ohci_hcd module that the AMD root hub uses.

That was it.
While compiling ehci module for my new card, I didn't understand I also needed another module to handle 1.1 USB on that card.
I'm glad it was that simple.
Thank you very much. |
