Ability to set report id for get_report
I'm trying to work with this device: http://www.cypress.com/file/298476/download
Sending commands seems to work fine (as noted, I can observe that a watchdog timer is activated when ENABLE_FWU is sent). However, I can't actually perform any of the read-back commands, because they require sending the report id along with the GET_REPORT request. AFAICT there is no way to do this?
If a report descriptor has no report ID 0 is assumed. So send with 0.
@ulao have you read the linked pdf?
