Hello,
on Christmas I buy Sony Xperia XZ1 - G8342 , but I in the box was only Sony UCB-20 cable (USB-C 2.0). So ... I buy cheap USB-C 3.1 cable , but it so bad , that if I plug it wrong way the transfer speed were 1MB/s , so like 2hours ago I got Sony UCB-30 (UCB-C 3.1Gen2 10Gbps) , but still got only 425mbps on USB tethering with UCB-30 cable . Even phone have only 35MB/s write speed , but the read speed are probably capped by USB2.0 because it go 60MB/s read speed. Does someone else have this problem ?
+ other thing with my motherboard , I can connect and transfer files only on my USB 3.1Gen2 ASMedia port , all other ports just connect disconnect the phone doens't matter if USB 3.0 USB 3.1gen1 , other devices like WD Elements (USB 3.0 external HDD) work as they should (+120MB/s transfer speed etc)
Googled about this more than +5hours , and even installed clean Win10 (1809) just for this, installed Xperia_XZ1_driver (link below) , in Xperia Companion I did Software repair , of course I did try other PCs too
