Didn't have this problem with -next-20120125. One of these commits, maybe?
next/drivers/usb/core$ git log --oneline next-20130125..next-20130204 -- *
2c2e865 usb: forbid memory allocation with I/O during bus reset
e9121a8 Merge remote-tracking branch 'usb/usb-next'
3b2ab2b Revert "usb: Register usb port's acpi power resources"
da0aa71 USB: add usb_hcd_{start,end}_port_resume
192fef1 usb: enable usb port device's async suspend.
f6cced1 usb: expose usb port's pm qos flags to user space
ad493e5 usb: add usb port auto power off mechanism
971fcd4 usb: add runtime pm support for usb port device
88bb965 usb: Register usb port's acpi power resources
54a3ac0 usb: Using correct way to clear usb3.0 device's remote wakeup feature.

I didn't see any changes in the drivers/hid/hid-logitech-dj.c or usbhid
but maybe it's doing something wrong anyway?

I'll open a bugzilla if a bunch more info is necessary.
