And who provides the cables all the time? Trezor.
There mini cables are not functional 99% of the time so why sell them from the beginning?
I don't have problem with the device If i get new cable the problem will be fixed. but this is not see easy to get new cable where i am at.
You, or one of your friends surely have an original microUSB cable from some older (or even new) smartphone. Try to use that and see if it works. If not, then it's a faulty device/port.
Should've been the first thing you must've done before purchasing another USB cable directly from them. I doubt with multiple new cables it's still the quality of cables at fault tho. Contact them and see what they're saying, maybe the fix is free.
