Raspberry Pico USB Host problem

[lKanifoll]

Hi!
I am trying to connect a device via USB to a Raspberry Pico. Faced the problem of getting the Configuration Descriptor which is 506 bytes long. As far as I understand, there is a bug with this in the chip itself, and there is a fix in the code called RP2040-E4.
As a result, multiple packets don't work. Any recomendations?

1. Firstly, make sure you use the latest code from this repo rather than one included by sdk.
2. If using latest still have issue, could you provide more information regarding your usb device, its configuration descriptors along with hid descriptor if any. Follow my comment here for how to retrieve it host_hid mouse data displaced raspberrypi/pico-sdk#442 (comment) . You could possibly find some useful info there.

1. Indeed, the tiny usb files were outdated. After updating the library, things only got worse... (see log)
2. Device is face recognition camera (i attached it's descriptors)

If i comment out this assert, multipacket works well, with the exception of parsing:

video class is not supported yet, for rp2040 only HID device (mouse, keyboard etc ..) would work now.

[lKanifoll]

I'm not interested in video class on this device, only cdc bulk conversation. I just set pointer in descriptor parser to cdc start byte and it init only cdc endpoints.

[hathach]

cdc on pico doesn't work yet either due to how rp2040 host manage its non-interrupt transfer #925 . Currently only HID class with interrupt transfer would work well. msc and cdc still need more work.
