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

RF_6052 = 4
B-cut are these ones:

thank you.

Yes, but not a bug for the devices that it is supposed to support! No one ever
says that their driver will support *future* devices! As I said earlier, there
are newer versions of the RTL8188C chip that requires different programming,
which may be the cause of the problem. On the other hand, the chip change did
not cause a crash in rtl8192ce. I just didn't work very well. As I have no such
device, I cannot test any changes; therefore, I will not make them. If you want
to write patches that let that device work with the kernel driver, I will be
happy to review them.

What difference does it make what chip it has? It is obviously some flavor of
RTL8188CU/RTL8192CU that is different enough that it does not work with the
kernel version of rtl8192cu. A few months ago, I ran across a new B-CUT
RTL8188CE that took new programming for rtl8192ce, and I suspect this device
also has the B-CUT chip.
The crash on unloading is a known fault of the vendor driver. It happens with
devices that work OK with the standard rtl8192cu. I have no desire to find out
what causes the crash.
If someone wants to supply me with a sample of this 0bda:819a device, I'll make
it work in the kernel. I have no desire to try to purchase one on my own.
