Just tested: wMaxPacketSize is 512 whil I'm sending 1-2 bytes at once so that can't be it.

Transfers before the timeout work. I can send as much as I want without any issues and the device can read it correctly. The writes only fail after reading has timed out.

That was the way I initially implemented it. I've added it to see if I maybe need to set different ID's for in/out. Doesn't change anything though :/

The code is still a mess while I'm trying to get it working. The most relevant files would be: * The main entry point: https://code.kulupu.party/thesuess/m8c/src/branch/wip/broken-usb-comms/src/switch_debug.c * The usb handling code: https://code.kulupu.party/thesuess/m8c/src/branch/wip/broken-usb-c...

My sysnand is broken, that's why I was catious to update

Updated to the latest firmware now and am still encountering the same issue

Continuing my journey to communicate with a serial device over USB, I've managed to establish communications in both directions which is already way more than I expected to ever get running. The last issue I'm facing happens when posting on the out session after calling usbHsEpPostBufferAsync . If t...

Found my issue.... I had sys-con loaded which claims all USB devices... Thanks for the help, learnt a lot about USB and the switch while debugging this. Now to actually talking to the device...

Sadly, that didn't work either in my case. I tried matching against the VID/PID with no results.

I'm not sure if I got the right values, so I'd like to just dump everything the switch sees - Is it possible to build a filter which matches almost every device?

I'm porting an existing tool to the switch and the last piece of the puzzle is communicating with a device attached to the USB port. The existing implementation supports either libserial or libusb, both of which seem to be incompatible with the switch. I think I should be able to rewrite the communi...
