Won't boot with USB Mouse plugged in.

[MajinBlayze]

I have a usb mouse and keyboard wireless combo that I have had varying success in working with different updates and kernel upgrades/recompiles. My current problem is that the system boots fine with just the keyboard plugged in (ps/2), and plugging in the USB mouse afterwards causes the kernel to hang after printing:
ohci_hcd 0000:00:... unlink after no-IRQ? controller is probably using the wrong IRQ

plugging in the mouse after boot causes this message in dmesg:
ohci_hcd 0000:00:03:0 auto-wakeup
usb 2-2: new low speed USB device using ohci_hcd and address 2
usb 2-2: configuration #1 chosen from 1 choice
input: Microsoft Microsoft Wireless Optical Desktop 2.20 as /class/input/input2
input: USB HID v1.11 Mouse [Microsoft Microsoft Wireless Optical Desktop 2.20I on usb-0000:00:03.0-2

I'm using kernel 2.6.19-gentoo-45 (since 20 doesn't work with unionfs yet)
all usb related drivers that I use are compiled into the kernel, compiled as modules makes things much worse.

Thanks in advance for your help, if there is anything else I could include to help troubleshoot, let me know.
