Jan Axelson:
Go back to working code and try again.

After removing something, be sure all length values in the report descriptor are correct.

Be sure to uninstall before changing firmware. 

There is no HID-class request 00h. I don't know what "Other Target" means.

yeah I can put the working code in and it runs fine but every time I try to remove one of these needed reports it does this. MY report is calculated with a built in size of command.  I do always uninstall first.

Strange though I think my size is wrong.
05C0h 1472 bytes  with it removed.
0503h 1283 bytes  with it present.
seems backwards.



 I agree  "other" does not tell us much.  I see it always calls it other target? The errors looks to be INVALID_PARAMETER but not sure what it is referring to. Strangely after the error I get more control transfers from this "other target".

re-ran the log and here is the last control transfer (Ex) I get
  URB Control Transfer Ex succeeded
Device Object   USBPDO-16
Driver Object   usbhub

URB Function   URB_FUNCTION_CONTROL_TRANSFER_EX

then after that I get this error

I can really capture the log but here is the over view. Not sure the yellow is ralated or not?
