Hello,

starting with v5.14-rc1, my kernel log gets flooded with messages

  hid-generic 0003:051D:0002.0002: control queue full

at rate of ~33 per second. Device 051d:0002 is an APC UPS (BR-650 VA).
I bisected the issue to commit

  7652dd2c5cb7 ("USB: core: Check buffer length matches wLength for control transfers")

Reverting this commit on top of v5.14-rc6 resolves the issue. I suspect
the problem is some missing cleanup when usb_submit_urb() bails out on
the newly added check but I'm not familiar enough with the code to see
what is missing or if the problem is on USB or HID side.

Michal
