Hi, I have a box here which has a couple of USB devices connected. That includes several HID devices (keyboards, mouse) and a couple of others including a USB powerswitch driven through a user space program. Now what happened is that I changed some of the HID devices around (moving from a direct port to a hub) and also moved the USB power switch from one port to another. But after that the power switch didn't work anymore, just giving a flood of usb 2-2: usbfs: interface 0 claimed by usbhid while 'sispm' sets config #1 (sispm is the user space driver) Kernel is 2.6.28-rc3 Relevant messages from the kernel log (relatively long because there is a longer history): ... ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver ehci_hcd 0000:00:1d.7: PCI INT A ->
