avrdude7.2 unable to detect atmelice - works with avrdude6.3

[feroze-mohamed]

I have been using avrdude6.3 on windows 10 and 11 without issues.

But lately we needed support for ATTINY1626, so upgraded to v7.2

While 6.3 works (detects atmelice) , v7.2 says unable to detect the atmelice

used ZADIG to change the driver to libusb

v7.2 :

v6.3:

[MCUdude]

Using Zadig, can you try to change your driver to WinUSB and see if this helps?

[feroze-mohamed]

Thank you for the response.

libusb works for 6.3

however as you mentioned i changed the driver for interface 0 as below

but same issue.

[MCUdude]

OK. You may have to use the original driver. I think it's called hidusb.
You can't use Zadig to select this, but you can do it under the Windows Device Manager.
On the bright size, this is the same driver as Atmel Studio uses, so one doesn't need to switch between drivers anymore.

I tested on another laptop where ATMEL STUDIO works without any driver change but it gives similar error:
I thought that was due to not using ZADIG. but as per your inputs this should have worked correct ?

avrdude error: no device found matching VID 0x03eb and PID list: 0x2141 
avrdude error: unable to open programmer atmelice on port usb 
avrdude done.  Thank you.

I don't use Windows on a regular basis, so I don't really know. @mcuee would have to chime in.

@feroze-mohamed

Please do not use Zadig to change driver but rather using the original driver from Atmel.

Please try my MinGW build to see if it works.
https://github.com/mcuee/avrdude/releases/tag/v7.2

For example:
avrdude-v7.2_mingw64.zip

If the above build works (using libusb-1.0+libusb-compat-0.1) and the offcial Windows binary (using avrdude-libusb) does not work, it could be that you hit the existing bug.

• avrdude MSVC build problem with USB composite device (avrdude-libusb library issue) -- low priority #968

[feroze-mohamed]

Thank you WIll update my findings

[feroze-mohamed]

offcial

on my windows 11 "avrdude-v7.2_mingw64" didnt work with libusb but worked with WinUSB v6.1.xxxx (using Zadig)

I need to try this on the remote system i was facing issue with.

[feroze-mohamed]

ok so i have no clue whats hapennign but its working so thats good news for me.

I am using the mingw version you shared and it works great with LIBUSB driver on the remote system that initially i was having issues with . so this is great news and thank you a lot.

however on my system same mingw version works with WINUSB but not with LIBUSB

Basically both systesm work with mingw version with different drivers.

Thank you for your support
