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

VERSION_NORMAL_TSMC_CHIP_88C = 0x0008

RF_6052 = 4



B-cut are these ones:
VERSION_NORMAL_UMC_CHIP_8723_1T1R_B_CUT =       0x1089
VERSION_NORMAL_UMC_CHIP_88C_B_CUT =             0x1088
VERSION_NORMAL_UMC_CHIP_92C_B_CUT =             0x10a8
VERSION_NORMAL_UMC_CHIP_92C_1T2R_B_CUT =        0x1090


thank you.
