Another solution would be to reset the android os, if this can be done, I see there is a system reset option in the android settings, dont know what happens if I click that.
IMHO very bad idea. If (this only one) module is not automatically loaded and manual loading (modprobe or insmod) does nothing, then we know about two possibilities: usb is not working properly (cold joint, etc) or this usb wifi card is not supported in this module. Linux kernel has drivers for almost anything, but You have to compile it, but we don't have source code - because Rigol gives sh*t about comply with GPL licence
as I said previously - they don't have any reason to not give us those sources (app is a separate thing because it works in a userspace).
We can send 100 emails to Rigol and most likely, again they will do nothing. They don't care about important bugs in scope software or their requirement to send source code for anybody who ask for it.
So buy another usb card or go to another scope brand than sh*tty Rigol.
