After some more researching, I found interesting idea for 8 years old laptop: realtek rtl8191su inside d-link dwa-131 adapter.
http://www.undeadly.org/cgi?action=article&sid=20101216231634 My thinkering is that usb adapter uses less power than pcmcia. The driver is rsu. Laptop is HP nx9020 with 2 usb ports: none2@pci0:0:29:0: class=0x0c0300 card=0x3084103c chip=0x24c28086 rev=0x03 hdr=0x00 vendor = 'Intel Corporation' device = '82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller *1' class = serial bus subclass = USB none3@pci0:0:29:1: class=0x0c0300 card=0x3084103c chip=0x24c48086 rev=0x03 hdr=0x00 vendor = 'Intel Corporation' device = '82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller *2' class = serial bus subclass = USB none4@pci0:0:29:2: class=0x0c0300 card=0x3084103c chip=0x24c78086 rev=0x03 hdr=0x00 vendor = 'Intel Corporation' device = '82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller *3' class = serial bus subclass = USB none5@pci0:0:29:7: class=0x0c0320 card=0x3084103c chip=0x24cd8086 rev=0x03 hdr=0x00 vendor = 'Intel Corporation' device = '82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB 2.0 EHCI Controller' class = serial bus I assume usb is able to power this adapter and run at sufficient speed? Is this good idea at all? Best regards Zoran
