Recommended USB3/SuperSpeed gadget device

Recommended USB3/SuperSpeed gadget device

[Andrey Konovalov]

Hi!

What is the recommended driver/device to test USB3/SuperSpeed gadgets?
Ideally something cheap, but at the same time with good driver
support.

I have a EC3380-AB board [1], which kind of works with net2280 driver,
but it passes almost none of the usbtest tests with g_zero (only tests
#1 and #9). I need something better.

Thanks!

Just to clarify: I mean a UDC device/driver, not a host one.

You have a unique chance to fix those problems :-)

If you're not willing to do that, I anything using dwc3 (dragonboard,
beaglebone AI, and many many others) would be good here.

It would be awesome to get that board working properly, as it's a
really compact solution that fits into an ExpressCard slot on older
laptops. My current priority is to figure out a testing setup for Raw
Gadget though.

All DragonBoards that I found have USB 2.0 device ports AFAIU, but
BeagleBone AI looks like what I need. Thanks!

While looking for a board with USB 3.0 device support, I've also found
the UP board [1]. I'm not sure which driver it uses though.

Oh, they put a USB2.0 only connector. That sucks, as it actually has
dwc3 inside.

beware that beaglebone AI runs quite hot. Get yourself some beefy
heatsink and a fan. Also, make sure to get the non-standard serial cable.

It uses dwc3. It's Intel CherryTrail inside. Heikki and Andy (Cc) should
have information about those, hopefully.
