Greetings, Over the past year, in an effort to convert my server farm to wireless, I've purchased some half a dozen USB wireless dongles, at a total cost of ~150.00. Unfortunately, none of them are (yet) supported — I know, I know, I've already had this debate with both dev's, & users. On the up-side, I've devised a resource that will greatly assist would-be adopters in selecting, and researching these, and other adapters _currently supported_ under under FreeBSD. That said; the adapter I most recently purchased, is quite nice (Cisco(Linksys) AE2500 Wireless-N). Boasts 2.5/5GHz @300Mbps. I figured (wrongly) because Linksys is so well supported on FreeBSD, that the likelihood of this being supported would be good. At any rate, given it's not, and because I _do_ have the Window$ drivers on the install CD. What are the possibilities I can reverse-engineer the drivers into a FreeBSD loadable module? I can unpack the setup file to extract the .sys files. While I _could_ utilize the ndisulator to load them, that's not my goal. Should I unpack the .sys file, and attempt to decompile/disassemble it? Or attempt to load it, and dump it from memory? — hacker/cracker advice _strongly_ desired — ############## #usbconfig -d ugen1.2 dump_device_desc ugen1.2: <Linksys AE2500 Cisco> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON bLength = 0x0012 bDescriptorType = 0x0001 bcdUSB = 0x0200 bDeviceClass = 0x00ff bDeviceSubClass = 0x0000 bDeviceProtocol = 0x0000 bMaxPacketSize0 = 0x0040 idVendor = 0x13b1 idProduct = 0x003a bcdDevice = 0x0001 iManufacturer = 0x0001 <Cisco> iProduct = 0x0002 <Linksys AE2500> iSerialNumber = 0x0003 <000000000001> bNumConfigurations = 0x0001 ############## P.S.
