This was a really helpful hint! Thank you Sergei!
I just tried to limit USB_MAX_XFER_BLK to 1/8 of the original value
(65535 -> 8191) and this time the transfer works without timeouts.
As we have a customer who needs this working as soon as possible my
question now is how to properly solve this.
Should I generally limit USB_MAX_XFER_BLK in my u-boot to avoid these
errors? Which value to choose?
