Greetings,

I abandoned trying to get serial working, did a quick test to see if the adapter automatically changed RX/TX.
Only used some tape so cant be sure of course but that didnt work.
Using U+POWERON to enter USBBOOT seemed to work somewhat. I get a new usb device and its able
to detect the usb:
usb 1-4: new high speed USB device using ehci_hcd and address 22
usb 1-4: configuration #1 chosen from 1 choice
----------------------------
I get this while trying to run usbboot "boot" line:
