Why can’t anything be as easy as it looks?
I’ve spent the past two days trying to get my Tek TDS2024B to talk to a Linux box via a homebrew USB-TMC driver library. Based on the USB-TMC spec, I’m doing everything by the book — and in fact, I can get the scope to respond to a GET_CAPABILITIES control request. Problem is, as soon as I try and send a command over the Bulk endpoint, it times out.
Urgh. I’m going to spend a few minutes reading through some libusb sample code, then if I still can’t get it going I’ll try and finish reverse-engineering the nasty binary serial protocol the HM8130-3 signal generator uses.
