Windows unsupported? #24

Closed maxgerhardt closed 1 year ago

maxgerhardt commented 1 year ago

Using the latest binaries from the CI (02e8d68055968368b73fa7560ee7e03102960d6b) for Windows

Using the latest binaries from the CI in Ubuntu 22.04

Why are there binaries for Windows available when it can't do anything? 😅

maxgerhardt commented 1 year ago

Thanks to having MounRiver Studio installed previously, the drivers I'm getting are the wch.cn ones.

Does this expect WinUSB or LibUSB and can't work with the official WCH.cn drivers?

andelf commented 1 year ago

Yes. libusb requires the libusb/WinUSB drivers to work.

andelf commented 1 year ago

The underlying error is reported by libusb_set_auto_detach_kernel_driver. libusb requires a generic USB driver to work with.

Added this note to README.

maxgerhardt commented 1 year ago

Can we modify the program to print a more helpful error message if this error occurs? "Likely no WinUSB / LibUSB drivers installed, please use Zadig.."

andelf commented 1 year ago

Good point. Added in be71a08

maxgerhardt commented 1 year ago

Great! I'll retry on Windows + Linux later today to make sure the error messages trigger and communication works with WinUSB/LibUSB drivers, then the issue can be closed.

maxgerhardt commented 1 year ago

Works on WinUSB drivers.

Without them I get the new error message

Note: The CI action for the Rust build has not triggered for the latest code changes, I had to fork it and trigger it myself.
