Hi again,
probably did you mean SD card reader instead of smart card reader?
In this case:
1) SD card reader is PCI device, not USB device:
lspci
...
03:01.2 SD Host controller: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro
Host Adapter (rev 21) (prog-if 01)
...
AFAIK, it needs SDHCI PCI driver.
2) Similarly as smart card reader, SD reader is also usually not
recognized by BIOS (it is not possible to boot from this device - at
least on my notebook - but I did not check if there exists some BIOS
settings which can enable another behavior).
BR,
Ales
Hi,
what do you mean exactly by "GRUB does not detect this device"?
1) Do you mean it is not listed by "usb" command?
2) Or do you mean it is not listed by "ls" command as disk?
In the case 2) it is most probably caused by this: Such device is not
mass storage class device. I.e., it probably needs some additional
special driver.
You can check this by lsusb -v
Mass storage device should have something like this (important are
values in last three rows):
...
Interface Descriptor:
bLength 9
bDescriptorType 4
bInterfaceNumber 0
bAlternateSetting 0
bNumEndpoints 2
bInterfaceClass 8 Mass Storage
bInterfaceSubClass 6 SCSI
bInterfaceProtocol 80 Bulk-Only
...
I have Dell Latitude E6500 - there is also smart card reader (connected
directly to UHCI controller) and its interface descriptor unfortunately
looks like this:
...
Interface Descriptor:
bLength 9
bDescriptorType 4
bInterfaceNumber 0
bAlternateSetting 0
bNumEndpoints 3
bInterfaceClass 254 Application Specific Interface
bInterfaceSubClass 0
bInterfaceProtocol 0
...
Additionally - this smart card reader device is (AFAIK) also usually not
recognized by BIOS (it is not possible to boot from this device - at
least on my notebook).
BR,
Ales

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. The devices looks like it is a USB 1.0/1.1 device,
probably sitting behind some hub to the EHCI-controller.
As far as I can tell, this machine does not have a companion UHCI
controller at all.
GRUB does not detect this device. I had a older machine with the same
broadcom smart card reader but sitting on a companion controller UHCI.
That worked just fine.
Regards,
Christian
