USB problems with windows 10

Post by richardb » Fri Mar 05, 2021 10:25 am

Has anyone noticed usb problems with windows 10? We have a few older products that use USB hid, where we haven't changed firmware for a few years and we are starting to see connection problems on some computers, has anyone noticed this happening?

I haven't personally seen any issues with HID and win10 (yet). It's unusual for HID to give problems (unlike CDC which nearly always has a driver issue). When you say connection issues, is it connecting then dropping off? Or does it sometimes fail to connect completely? It could possibly be a descriptor issue? What version of the Swordfish USB library are you using?

Hi David, thanks for the quick reply, It's not completely clear to me yet whats going on as i'm not onsite very often and the information is a little second hand for me. but i was told it if sometimes fails to connect completely.

but it will be an older driver as the firmware hasn't been changed for years. production normally just go to a folder on a shared drive for the program files, in fact I've just checked the hex file is from 2015-11-04.

It's feeling like a windows thing but i don't really know.

I'm going in monday and i'll try and get more information.

I was just wondering if other people had seen this on older hardware, obviously the concern for us is we will start getting customers having problems after a windows update, now that you cant easily opt out of windows 10 updates.

PS still love the compiler even after all these years.

I would love to pay for something like swordfish/firewing for STM32H7's ;)

If it's been running fine for your but now your are getting multiple reports of the same problem, it could be a win10 issue. I've seen similar problems in the past (but not HID related) where the rules behind a driver implementation are tightened up - showing up a problem that was there from the beginning. That's why I mentioned to check out you descriptor.
