Both in X and out of X there is no mouse. The 2.4 kernel hotplugs it, and it works fine in and out of X. Its a usb mouse, and I've read about the usb issues after ugrading to 2.6 (none have helped). All help is appreciated.

i had same prob but found no solution, i used 2.4 and had my PS2 mouse work fine and upgraded to 2.6 and my PS2 mouse stopped working, strnage espicaly cause of the port type. i cant helpjsut wanted to say your not alone in 2.6 mouse issues

I tried putting usbhid in modules, like many 2.6 upgrade guide say to do, and it didn't work. Any suggestions?

Could the problem be that I compiled USB hid support into the kernel instead of a module?

Alright, I recompiled with usbhid as a module instead of built in, and nothing changes, no mouse...
Any ideas?

Same here. upgraded from 2.4.31 to 2.6.15.3 nomouse. touchpad works, which i dont want it to but no mouse : (

I was able to fix it by the way. I'm pretty sure it was the usb 1.1 support; make sure you compile that.

After looking through my .config I noticed what the problem was - reading what OHCI was all about, that's what I had left out.
I did not include OHCI or UHCI in the original config.
Both are included as Modules now and Logitech Wireless USB Mouse is working a real treat!! (And the Synaptic touch pad works simultaneously no problems)

# USB Host Controller Drivers
CONFIG_USB_EHCI_HCD
CONFIG_USB_OHCI_HCD
CONFIG_USB_UHCI_HCD

# USB support
CONFIG_USB_ARCH_HAS_HCD=y
CONFIG_USB_ARCH_HAS_OHCI=y
CONFIG_USB=m

found this in another post. recompiled with those options (already had one of them) and works great!
