David,
I've got an "OnTrak" ADU208. It's a USB device that has 8 relays and 8 ttl inputs. The documentation says it uses two interupt endpoints ... one input and one output. It seems to expect small text commands.
ok
Now... firstly, uhid is probing it as uhid0:
uhid0: www.ontrak.net ADU208 USB Relay I/O Interface, rev 1.10/0.00, addr 4,
iclass 3/0
... I don't know if this is hindering me. The usbhid* commands aren't particularly helpful. The port udesc_dump seems only to work on ugen devices ... and ugen doesn't pop up for this device.
how about getting usb hid descriptor, parsing and dumping it? check out libusbhid - man usbhid(3). it might be that all you need to do is to create hid report and send it to the device. libusbhid(3) will help you with that.
I suppose I need to know how to supress uhid ... or to make ugen show up. It would also be nice to know how to generically poke the interupt enpoints...
well comment out 'device uhid' from your kernel config and rebuilding the kernel should do the trick.
