Note that this is probably not normally a purchase-able device (unless maybe you have a Pavilion and need a replacement under warranty or something like that) as it comes packaged/shaped/sized with custom bracket and face-plate to fit only on Pavilion and maybe other HP boxes.

But, if you have a Pavilion and are wondering if the 15-in-1 card reader will work with Linux, it seems the answer is 'yes'.

I got this device out of a near-new Pavilion box I found on the roadside :) minus its motherboard, and made a new front bezel out of a case blank to fit my case, and mounted it into a shortened metal housing of a gutted CDROM drive. It fits in an unused bay and works great, at least with the only CF card I own, which is a 128MB Lexar SD card from a HP Photosmart 320 camera.

During boot, the thing appears as 4 SCSI removable disks sda, sdb, sdc, sdd, and when I insert a card into the SD slot, the green light lights and a /dev/sd1 appears, which can be mounted using a normal fstab entry with 'auto' as the filesystem.

The kernel USB Mass Storage driver seems to be all that's needed to access it.

I give it a 9/10 only because it's packaged to fit only a select few boxes (HP ones, not generic cases) but a person could make an external housing for it or mount it as I did. For the price, I am not complaining.
