thanks gosh you are here. i went sigrok looking for HANTEK LA5034 logic analyzer driver but sadly none. and your site is "sure" some confusing site for me. do you plan to RE the LA5034? just the windows driver and API?

@saturation - don't be scared of "software" it's just a cookbook !!!. is there anything bad in being an "Linux guy" ? if you did not had any UNIX guys around till now then you may have found one :)
I said I will run it under a VM because that way the USB data stream passes through the host OS I/O channels, there is a module called usbmon and I can capture the whole traffic without needing an expensive hardware USB analyzer .. there are few tools on WIN that do something similar with what usbmon does that but they pretty much suck compared with the tools I have @ my disposition on Linux.
"biot" ... You are saying you got the protocol "decoded" or am I reading wrong ?

Unfortunately none of us have an LA5034, and we do have a ton of other devices in the pipeline, so no concrete plans. You can help to make it a reality -- start by creating a device page on the wiki, with good detailed pictures and description of the device. Writing a driver is really not that hard, lots of example code.
The sigrok project never uses vendor-provided drivers or APIs. We only use vendor firmware if necessary, and not even that for Cypress FX2-based devices -- wrote our own for that.

Yes. As you say, running the vendor-provided software in a VM and using usbmon is all you really need.

send me link on how to write a driver, sniffing the protocol etc, what tool/equipment needed etc. if its within my budget, maybe i can get the LA5034. fyi: that device already has an API and driver, but not documented, if there is method/tool to RE the exportable functions in there (how to call functions and its arguments/parameters) i think that is much quicker than rebuilding API+driver from scratch. thanks.
