I would like to, but unfortunately I lost access to this really rare hardware
about a month ago. It is a Qualcomm device (0x05c6:0x9025) with a slightly
modified firmware to rebrand it as a Cellient product with a different vendor
id. How to proceed here, if I have no access to it anymore? Drop it?
