Someone reported an issue related to that in 2006 on the Japanese debian-users list: http://lists.debian.or.jp/debian-users/200608/msg00010.html They were using a Debian kernel based on 2.6.17, and based on the dmesg output both usb-storage and pegasus drivers try to claim the device. I'll paste some excerpts below. Since a quirk entry in unusual-devs.h would only apply to usb-storage, it should not cause additional problems for a USB-Ethernet device with the same ID, right? I guess it would be necessary to blacklist the pegasus module in order to use a Buffalo USB-SCSI cable (with or without quirk). usb 2-1: new full speed USB device using uhci_hcd and address 4 usb 2-1: configuration #1 chosen from 1 choice Initializing USB Mass Storage driver... scsi0 : SCSI emulation for USB Mass Storage devices usbcore: registered new driver usb-storage USB Mass Storage support registered. usb-storage: device found at 4 usb-storage: waiting for device to settle before scanning pegasus: v0.6.13 (2005/11/13), Pegasus/Pegasus II USB Ethernet driver usbcore: registered new driver pegasus usb 2-1: reset full speed USB device using uhci_hcd and address 4 usb 2-1: reset full speed USB device using uhci_hcd and address 4 usb 2-1: reset full speed USB device using uhci_hcd and address 4 usb 2-1: reset full speed USB device using uhci_hcd and address 4 usb-storage: device scan complete lsusb reported Bus 002 Device 010: ID 0411:0001 MelCo., Inc.
