I've been working for some two weeks observing the behaviour of rtl8187B. Thanks to someone's report (I think it was Rogerio's), I found the realtek driver. It does seem to work a little better regarding transmission. I have taken a look at the driver (it's GPLed) and done some experiments, but couldn't find any particular difference that magically make it work yet. I think the mmiotrace is not exactly what you want. Since these are USB devices, usbmon dumps are much more readable and useful. I've made some of my own, but still need to write some scripts to translate them to something I can read and compare more easily. As soon as I get some patches that work for me and are field tested for these particular device versions, I will send them to the list for review and testing with other device versions. Larry, you mentioned in one of your messages about the specs. Are they under an NDA or could you provide or ask for a copy? At a glance, the realtek driver seems to do some dynamic power gain control. I will try this as one of my next steps.
