I thought they would work fine with TPL, isn't it? # hciconfig hci0 inqtpl hci0: Type: USB BD Address: 00:19:DB:xx:xx:xx ACL MTU: 310:10 SCO MTU: 64:8 Inquiry transmit power level: 4 # hcidump -X -V < HCI Command: Read Inquiry Response Transmit Power Level (0x03|0x0058) plen 0 > HCI Event: Command Complete (0x0e) plen 5 Read Inquiry Response Transmit Power Level (0x03|0x0058) ncmd 1 status 0x00 level 4 Looks all good to me and works perfectly fine with the CSR dongle, I tested this with.
