PICKit 4, SNAP, Atmel ICE and Power Debugger only work with hidapi but not libusb

[mcuee]

From here:

• PICkit4 and SNAP serial numbers not read by Avrdude #1038 (comment)

For this test, I build avrdude without hidapi support. And I make sure the hid drver is already detached and then libusb is used.

hidapi version works fine (with hidapi-libusb backend). So there is a bug here in git main.

Same result under Windows.

I built avrdude without hidapi and readline support in this test.

I also tried with the default Windows HID driver (libusb-1.0 under Windows supports HID driver), or with WinUSB driver. The results are the same.

I'll assume the SNAP is also affected.

But how about other, "older" JTAG3 compatible programmers such as the Xplained Mini ATtiny817?

It seems to work with WinUSB driver. I am using the Xplained Pro Attiny817 for this test.

It also works under Linux even though there is a warning.

Cool! I think we're on our own though. IIRC, no JTAG3 programmer will work with Microchip Studio if not using the hidapi driver.

Yes we are on our own as Microchip Studio and MPLAB X use native Windows HID API under Windows and not hidapi/libusb. But I think we should be able to figure out the issue as hidapi-libusb works under Linux -- therefore libusb should also work.

MPLAB X under macOS and Linux may use HIDAPI (I need to double check) for HID device. They for sure use libusb-1.0 under macOS and Linux with generic USB devices (not HID devices).

And this is not an important issue either as HIDAPI works, so Windows/macOS/Linux all work. FreeBSD should also work.

[mcuee]

BTW, this is not only applicable to UPDI, but also ISP.

Tested under Windows with either WinUSB driver.
