Have latest firmware 220.127.116.11. Works on any other computer. I’m using 12W adapter and have set max_usb_current=1 in config.txt. Drive spins fine up but is not recognized. At the same time, all other usb storage devices (flash drives) also dissapear.
devcon status *
Shows several entries like this:
The device has the following problem: 28
Problem status: 0xC0000490
Code 28: The drivers for this device are not installed.
Seems the Ultra trashes the usb controller\driver\Windows, probably because of SES.
Is there a way to remove SES? Going to try to flash the non-Ultra firmware on it, but imagine it wont work.
