[BBB] RTL8188EE not mounting

[BBB] RTL8188EE not mounting

[Cameron B Skinner]

[-- Attachment #1.1: Type: text/plain, Size: 945 bytes --]

Let me start by apologizing if the outcome is very obvious to everyone but me. I'm VERY new to Linux and newer to Yocto.

I have an RTL8188EE wifi board that I'm connecting to a Beaglebone Black via USB. If I do an 'lsusb' I can see that there is a Realtek device out there somewhere. Even though the driver for this exact device appears in the kernel drivers, the device doesn't mount. I'm running the dizzy version and have tried building the Sato, Full Command Line and Basic versions hoping that one of them would include whatever it is that I need to recognize this device.

For the non-Sato versions I did copy the uImage and Modules to the SD card thinking they might help.

Any help would be great.

TIA

For this device to work you need both a kernel driver and
firmware.  The kernel driver is probably being built, but
the firmware is probably not installed.

Make sure your image includes the appropriate firmware for
the device.  In your case I think this would be linux-firmware-rtl8192ce

Does the appropriate driver get loaded into the kernel?  What
does 'lsmod' show?

If you still have trouble, send the output of 'lsmod' and 'dmesg'
after you plug in the device.

Thanks for the reply. Your analysis is likely correct. The 'lsmod' command had no mention of the Realtek device. The 'dmesg' command indicated that the Realtek device listed under 'lsusb' device 5 was using musb-hdrc similar to the rest of the USB devices, but it did not indicate anything more than that, whereas the keyboard had more information following it.
