Installation on USB3 computer

Worked for me. :)

I was prepared to deal with that, too (digged out of my cellar an old USB hub). But I did not need it at all, on an ASUS laptop with UBU18! I thought also to remember Jolla mentioned to have this solved? Seems not (which is a pity and PITA). So only chance for you seems to grab any old USB hub from a friend/office/ebay... (or what about trying a VM without USB3 support?)

I was prepared year ago, but how on earth is the problem still not solved? At least for USB 3.1 controllers and ports, the command to force USB 2.0 mode does not work correctly.

I tried VM with USB 1.1, but was not able to even connect the phone to the VM. This is ridiculous: Sony was so cheap they put USB 2.0 controller in Xperia XA2 and caused the whole problem, Fastboot developers are so incompetent they did not realise USB3 or Jolla is so lazy!

We need to be able to flash Sailfish OS on modern computers. Sailfish is not cheap alternative for poor people with old computers, especially with €50 price tag, so flashing script must work on modern computers!

sign it, had also problems with flashing xa2 but changed the usb port. but tbh i have no idea if the other port that did not work is a usb3 but after changing it worked fluently. but in the end the flashing should work on any usb port especially newer ones.

Try Manjaro Linux. I tried various Ubuntus and Debians, and threw them away eventually. Haven't looked back since. Application SDK works fine, too!
