Ok. :) Maybe I should explain better. :) I am not using the Smart Card reader to boot. Just to read cards. :) I have and am using several Smart Card Readers (not SD card. :)) in GRUB. They are all USB 2.0. The Broadcom 5880 that you and I have in our Dell laptops have two interfaces. One proprietary and one standard Smart card. The Broadcom 5880 is USB 1.0/1.1. I used to have Dell with a UHCI companion controller and this Broadcom device worked just fine, just like any other smart card reader. Now I have another Dell (E6430, core i7), _NO_ UHCI companion controller. Just EHCI/XHCI. Most modern machines are like this. The Broadcom card reader in this machine is still USB 1.0/1.1 is attached through some translating hub. On this machine, I can not see the Broadcom device in GRUB any more. That's my problem. :) > Dne 29.8.2013 09:10, Melki Christian (consultant) napsal(a): > > Hi, > > > > Is there a known problem with these devices in GRUB? > > > > I have a core i7 based Dell Latitude 6430 with an integrated broadcom > > smart card reader.
