Xiaomi 3G usb3.0 issue scsi

Installing and Using OpenWrt
1

Hi. I am using the Xiaomi 3g with the latest Stable firmware. I installed all packets for usb. But new usb 3.0 scsi hdd cases do not work. They are not recognized, so I can t mount them. I think it is some kind of driver issue. With 2.0 the NAS Speed with samba are limitied on my device to 60mb/down and 25mb/s up. An older 3.0 hdd case did work, but only improved speeds by about 5-10mb/s

Have you tried installing kmod-usb-storage-uas?

yes of course, this problem seems to be typical for xiaomi 3g router. other uses have that too. i coud only use a micro usb 2.0 cable. but then i loose speed

Same issue here. Its a kernel / uas driver bug.

Is there a way to "force" usb3/ Bulk only Transport mode instead of uas/uasp?
