It happens with devices that work OK with the standard rtl8192cu. I have no desire to find out what causes the crash. We were trying to know, loading the _realtek_ driver, the chip of the device. *Because*, as Thomas said before, doing: # echo "0bda 819a" > /sys/bus/usb/drivers/rtl8192cu/new_id with the rtl8192cu _kernel driver_ He got a _panic of the system_ . This is a severe bug in rtlwifi. BTW, the device is RTL8188C/RF6052 >> [ 183.370905] Chip Version ID: VERSION_NORMAL_TSMC_CHIP_88C. VERSION_NORMAL_TSMC_CHIP_88C = 0x0008 >> [ 183.608631] Set RF Chip ID to RF_6052 and RF type to 1T1R.
