I went off to the computer fair, to buy some memory for my Jornada.

There was stacks of fake memory sticks there.

I didn't see any fake SanDisk stuff, in fact I only saw one place with SanDisk stuff.

I wanted a 2GB CF Ultra II, but they didn't have any, only 1GB. They had 2 GB, but not Ultra II.

I couldn't find anyone else with SanDisk stuff, so I decided to get the 1 GB Ultra II. I looked at the packet carefully, noticed that it had the hologram on the box, and even though the card was in the pack upside down, the protective case didn't look like the one I'd seen fake ones in, and the sticker on the card had rounded corners.

I paid for it, and before leaving the table, I checked the manual in the box, it was the proper booklet with staples in it, not a folded photocopy. I moved away, took the card out, and checked the serial number, it looked legit, and it has the country it was made printed on it too.

I couldn't get a memory stick, they were all fake, except for one, which was only 512, and they wanted $72 for.

I also bought a usb wireless adapter for the machine I keep in the garage, so I won't have to drag cat5 over the balcony all the time, I got a CR2032 battery for the Jornada, and I got a PATA -> SATA adapter, to try to get a SATA disk working in a tivo.

I decided to test the usb wireless adapter in my laptop, even though I don't need it to work. It's a Dlink DWL-G122, which I've had working on my laptop before.

I plugged it in, and got:

[7275503.493000] usb 5-1: new high speed USB device using ehci_hcd and address 22

and nothing else.

The other one was version B1 though, and this is version C1, and the chipset has been changed.

I found this page which I used before, when I got the B1 version working.

I found references to the C1 version being based on the RT73 chipset (here). I went to the RA Link Tech support page but found no references to RT73 drivers.

I found people providing links to the drivers directly, but they resulted in a 404.

I googled around a bit more, found a cache of the page, and the RT73 was referred to with (RT2571W) following it.

On the current page, there's reference to "RT2571W/RT2671" and the link is to this file

I downloaded that, compiled it, copied the firmware and config file to the appropriate location, and inserted the kernel module.

Dmesg said:

[7278672.174000] rtusb init ====>
[7278672.175000] usbcore: registered new driver rt73

and nothing else.

No interface (rausb0) appeared.

I found this page where the guy has the same problem.

I also found this blog with the same deal, but this guy's got a Linksys device.

Apparently the reference drivers from RA Link Tech don't know about the USB device IDs attached to the adapter.

I used lsusb, and got:

Bus 005 Device 023: ID 07d1:3c03 D-Link System

confirming the same IDs.

I edited the rtmp_def.h file, but it's changed from the style both pages above referenced.

I added the following line:

{USB_DEVICE(0x07d1,0x3c03)}, /* Dlink */ \

right near the end of the file (before the end marker line)

I recompiled the driver/module, removed the old one, and inserted the new one.

Dmesg said:

I then did "sudo ifconfig", but there was no sign of rausb0. I tried "sudo ifconfig rausb0":

rausb0    Link encap:Ethernet  HWaddr 00:00:00:00:00:00

Ok, looking good. I tried "sudo iwconfig rausb0":

Good. "sudo iwconfig rausb0 essid any", "sudo iwconfig rausb0":

Connected, link light on device is on, all working.
