I ordered a Delkin Cardbus 32 CF adapter<\/a> last week. This was intended to solve the “what is the smallest device I can use, that doesn’t have any cables hanging off it, that’s still really fast, to copy CF (I\/II) cards to my laptop” problem… you know the one I mean. It’s a bit pricey (about 3x the cost of an external USB 2.0 reader), but it’s supposed to be as fast as Firewire or USB 2.0, and the form factor is great. <\/p>\n

Yesterday (in anticipation of delivery) I went to download the OSX drivers from Delkin. Bad news, the OSX beta<\/strong> drivers require that you “Shut down the computer and insert the CardBus adapter (with CF Card).” This is a major deal killer. I waited until I got the card this morning and tested. Sure enough, carefully eject the disk, power off the card from the menu, eject it, re-insert it and… voila, kernel-panic and a reboot (which does<\/strong> simplify the “shut down the computer” step, but not in a good way). Here’s what I’ve done to attempt to rectify the problem:<\/p>\n

1) Called Delkin support and asked “When will there be a production OSX driver?” He didn’t know, but assured me that they were working on it and he’d email me when it becomes available. I considered returning it, but it’s just one of those cases where I’d end up buying it again when the drivers came out, so why waste shipping…<\/p>\n

2) Learned a fair amount about Kernel Extensions in OSX. This is really cool stuff, and I’ve gotten to the point that I understand the problem… and know that I can’t fix it… which is basically a bad but interesting place to be. When you insert the Cardbus 32 card it loads an extension named CF32A.kext<\/i> (and a “personality” named NinjaSCSI<\/i> or something, I can’t remember and don’t want to reboot my machine again). If you manually load this extension using kextload<\/i> it can be unloaded and subsequent reloading\/unloading can be performed with no problem. But as soon as you actually insert the card it becomes impossible to unload the extension (using kextunload<\/i>). <\/p>\n

C’mon Delkin… just a little more work and this will be a really cool accessory!<\/p>\n","protected":false},"excerpt":{"rendered":"
