So, I removed my card reader from USB and everything works well. Using 5Ghz is not a solution, not all devices at my home support this frequency.
I'm really interested in the solution by Xiaomi. How do they switch between USB 2.0 & 3.0 programmatically? They have a check box in UI.
Hi @nbd, it was nice to meet you at Prague at OpenWrt Summit 2017. Do you have any hints on how could we force USB 2.0 drivers for Xiaomi 3G?
Thanks in advance!
