RTL8723AS-VAU
Hi tech@, Driver/help request: RTL8723AS-VAU either in urtwn or new driver. Found on: Lenovo IdeaPad Yoga 13 port 2 addr 3: high speed, power 500 mA, config 1, GW-USValue-EZ(0x7811), GW-USValue-EZ(0x7392), rev 2.00, iSerialNumber 00e04c01 - note serial number urtwn0 port 3 addr 4: high speed, power 500 mA, config 1, USB2.0-CRW(0x0129), Generic(0x0bda), rev 39.60, iSerialNumber 2010020139600 ugen0 (card in question) port 4 addr 5: high speed, self powered, config 1, 802.11n WLAN Adapter(0x1724), Realtek(0x0bda), rev 2.00, iSerialNumber 00e04c01 ugen1 ^ same serial urtwn1 at uhub2 port 4 Realtek 802.11n WLAN Adapter rev 2.00/2.00 addr 5 urtwn1: MAC/BB RTL8188CUS, RF 6052 1T1R, address fu:nf:un:fu:nf Pretty wild card, seeing as it has a PROPRIETARY USB CONNECTOR on the motherboard itself. It is detachable, but highly unlikely it'll plug into anything; its a weird rectangular connector. Hence, highly likely that only someone with this laptop can help. Also, someone can help by checking out chipset differences from classic urtwn and those used by Larry Finger's beta Linux driver for this card @ http://github.com/lwfinger/rtl8723au (doing this ATM) Yet someone else suggested adding the product ID to dev/usb/usbdevs and if_urtwn.c and changing loadfirmware to the strange and undocumented urtwn-rtl8723fw. Not much luck here, got - urtwn0: timeout waiting for firmware readiness I'm not a driver expert but can anyone tell if this card could be added to urtwn? Or would a whole new driver need to be implemented (due to the chipset)? Thanks! Jean
Re: Documentation for Realtek 8188* devices

I'm strugling to find any documentation for RTL8188* wireless devices (including those already supported in urtwn driver). I wrote to Realtek, but no responce followed. My problem is that I have a MiniPCI RTL8188CE device in my ThinkPad, and I want to try writing a driver for it. AFAIK RTL8188CE-VAU (supported in urtwn) is essencially RTL8188CE with USB bridge, so having access to documentation urtwn driver was based on would be very helpful. So, if anyone knows where these docs can be found, I would be very greatful. -- Dmitrij D. Czarkoff Hi Dmitrij, Wishing you the best finding documentation and receiving a response from Realtek. It is safe to say the latter has become my hobby... Not of preference but of perseverance. Anyway, I've picked up FreeBSD Device Drivers (Kong) which seems like an okay, albeit rough, place to start understanding drivers for OpenBSD (only real driver reference out there besides the tree), though adding support for the PCIe Mini routine of your device shouldn't be the most difficult feat ever, the cousin chip is already supported. Check out how other cards (iwn(4)) attach. I've an RTL8723AS-VAU which is reportedly a non-mass production analog to the 8192CU (also urtwn), except with a BT function. There is even a `urtwn-rtl8723fw' that comes with urtwn but no documentation on those magic numbers `8723'. We're on similar boats/rafts. Please post back your findings. Would be interested in helping you so as to help myself and others. Cheers. Sorry, swore this was sent to misc for non-tech content. Curses.
