SCR CAC reader for Leopard

For those of you in the Department of Defense...

I have acquired an SCR 331 CAC reader from work, in order to log in to OWA with my CAC card, but I can't get Leopard to recognize it. I plug it, a solid light comes on, but no joy. I can't see my CAC in keychain access. Is there a driver out there or some other trick so I can get my Mac to recognize the card reader?

iMac G5, iBook G4, Mac mini G4, 4G iPod, 5G iPod, iPhone 8GB, Mac OS X (10.5)

With the SCR-331, when you put your CAC card in the reader, you should get a flashing light. If the light's not flashing, the reader isn't reading the card.
My SCR-331 works fine in Leopard with no tricks or drivers, although I had to go to using an ActivIdentity Reader and ActivCard Gold in Parallels to do OWA because Safari just asks for my password repeatedly when I try to use OWA in Leopard.

I have an scr 331 firmware version 5.18 with the latest drivers from scr for osx installed. The reader is recognized by the computer. pcsc test completes succesfully. However the keychain does not show the existence of the reader. This is rapidly falling into the "too hard to do" category. If apple wants to sell more computers to the govt, they have got to figure this out.

I have a sore shoulder from lugging my wonderful but HEAVY 17" MacBook around. I'M READY TO BUY AN AIR!!! But Air's only come with Leopard, and I'm a federal employee and CAC user, so Apple won't let me buy one that I can use.

I got Leopard for Christmas, and installed it on my 17". I lost a LOT of passwords, bookmarks and other stuff when I implemented the only solution to get CAC access back - downgrading back to 10.4. Downgrading using the original restore discs, then doing all of the software updates to get back to 10.4.11, DID work. The same immediate, transparent hookup with the SCR-331.

I sent applefederal@apple.com, politely-worded inquiries on 10 January and 22 March, and have gotten NO RESPONSE WHATSOEVER to either inquiry.

I also e-mailed SCM (the SCR331 vendors,) who agreed to "investigate what we're doing," and they actually got back to me with a personal response, including a link to a supposed solution:

WOW! It requires somebody who knows a WHOLE lot more about his machine than I do, to install the appropriate patches manually at various places into his OS. I'm a senior systems engineer, but my machine is just a tool for me. This was like that commercial with the guy with a knife in one hand and the phone in the other, and his surgeon is telling him to make the incision in his abdomen...

I've searched the net pretty extensively, but from the black-hole silence at Apple, not even a hint of "we're working on it," my guess is that they've decided the federal market is not big enough to even try to resolve this issue, and they've written us off. Really, too ****** bad for us.

If you have the developer tools loaded, it's not that hard to get this working. I just had to install libusb-0.1.12 and then the updated drivers for the reader. After a reboot it worked fine.

libusb available from:

Similar here too - three different card readers now, and they just won't work on my G5 with 10.5.2 installed. I can get a partial download of images off of one of them, and have to keep reconnecting it until I get the lot. Another I just bought (off eBay), which works perfectly on my brother-in-laws old Sawtooth G4 with 10.4 installed, just refuses in 10.5.

I have put the same cards into the respective cameras (one CF and one xD), and they connect perfectly. My workflow means that reading from cards in a reader is better, but I'll have to download from the cameras for now.

I downloaded libusb, pcsc lite, and the scmccid files. I clicked the install unix files and restarted my computer. However it still doesn't show up in keychains. My password expires soon and I need to get a new password setup so I don't have to do the 7 day ones. It was a pain to set up before, but these files I downloaded, they don't really explain what to do, I'm pretty good with computers, but this is out of control.

This works fine with me; no modifications to my system were needed. I have a SCR-3310 CAC reader running under Leopard. I initially had difficulty logging into OWA, but it turned out that the sysadmins had to have a copy of some certificate in the server's "name store" for the Mac to access. Apparently my mac was trying to compare my CAC against something that wasn't on the server. Once they installed/mapped my certificate to my account, OWA worked fine. Point is, the problem wasn't on my end. Ask a SA for help, maybe their configuration is not setup correctly. It worked fine under ActivClient, just not the Mac until they mapped the certificate.

Mine was working great, too. SCR331 under 10.5.2 and earlier. I didn't have to do anything special to make it work - just plugged it in. However, the light never came on. Now I installed 10.5.3, and I am dead in the water. Let me know if you were working and now are dead since the upgrade to 10.5.3. I wonder if the problem is related to the firmware of the card for the others that are having problems?
