Larry, The various rtl8192xx drivers read the manufacturer-set channel plan into efuse.eeprom_channelplan, but ignore this and use efuse.channel_plan (which is never initialized) when deciding which channels to allow. The patch below allowed my device, purchased in Europe, to see channels 12 and 13 when configured with "iw reg set EC" It needs more work in order to accept being configured for arbitrary countries: would you like me to work on a more comprehensive patch?
Please - I have plenty to do. I had never had any problems with the allowed channels, as I use CRDA and it sets my domain to US, which is as restrictive as any.
I just tested, and the RTL8192CE that I have installed at the moment has 0xA (COUNTRY_CODE_WORLD_WIDE_13) in the eeprom, which happens to be what is set in rtlpriv->efuse.channel_plan in rtl8192ce. That is not surprising as the card came from Realtek and I would expect something appropriate for China.
