# 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.
