 Posted: Sun Jul 18, 2021 9:07 am Post subject: external usb cardreaders not working |
 |
|
The usb is working fine, I can use regular USB sticks, connect a USB GPS, an Arduino, rs232 interface and other things.
But when I use a card reader to read the SD card of my camera, it doesn't work. When I plug in the card it is not found. It is not found by fdisk either. It does not recognises anything. I tried serveral card readers but always the same result. It looks as if it only works when there is a "direct usb connection".

Spanik,
Unplug the card reader and remove any cards.
Wait 10 secs or so.
Plug the card reader in and look at the end of dmesg.
Post all the card reader messages since you plugged it in.
That will tell us about faults.
Also post the output of A few USB card readers need kernel modules.
Cameras sometimes use proprietary on disk formats too but that sounds like a potential problem for the future.

Sorry for the late reply but I went on a short break and forgot to take the offending card reader with me.
Plugging in the reader, then dmesg gives:
| Code: | [ 553.094279] [ 888.456848] usb 3-2: new high-speed USB device number 31 using xhci_hcd

When I next plug in an SD card dmesg reads:

Plugging this same cardreader in the desktop and then plugging in the same SD card:
| Code: | [ 4818.953864] usb 7-1: new high-speed USB device number 4 using xhci_hcd
[ 4819.218272] usb 7-1: New USB device found, idVendor=0bda, idProduct=0169, bcdDevice=61.23
[ 4819.218274] usb 7-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3

[ 4870.398042] sdg: sdg1 |
And the card shows in the automounter, can be mounted and read.
