Here is the chipset description that the rtl8xxxu driver prints on load: [ 8.097402] usb 1-1.4: RTL8723AU rev B (TSMC) 1T1R, TX queues 2, WiFi=1, BT=1, GPS=0, HI PA=0 What other details should I add about it? > Second, I really don't think this warrants a module parameter. Bumping > the value should suffice. Okay. Adding a module parameter was useful for me in debugging, and I thought it might be a useful backup option for other end-users who may find that the default value doesn't suffice. It seems plausible to me that the delay is due to waiting for some kind of analog circuit to stabilize (PLL, maybe?) and that there could be a large variation among devices. > Note that the patch should at least be relative to > wireless-drivers-next, or preferably my rtl8xxxu-devel tree.

Are you still unable to follow them in the second version of the patches that I submitted? (It appears that they were mangled by Gmane the first time I posted them.)
