Hello,
I bought an external DVD Device and want to connect it per USB to my recalbox on raspberry pi 3.
It seems to be regognized (dmesg output):
[ 1133.157280] scsi host136: usb-storage 1-1.4:1.0
[ 1134.155843] scsi 136:0:0:0: CD-ROM Optiarc DVD RW AD-7700S 1.B0 PQ: 0 ANSI: 0
[ 1134.160049] sr 136:0:0:0: [sr0] scsi3-mmc drive: 24x/24x writer dvd-ram cd/rw xa/form2 cdda tray
[ 1134.160680] sr 136:0:0:0: Attached scsi CD-ROM sr0
But I cannot access its contents. (I cannot mount it etc.) It everytime tells me that there is no medium inserted (I tried several CDs and DVDs)
I think there are two possible error causes:
- the device gets not enough power from the usb ports on raspberry
- there is no (correct) driver for that DVD drive installed
How can I check which cause is correct? I tried to connect it to my WIN 7 box and it works (so the device is not broken). I noticed that on windows it "spins up" but on recalbox it does not spin at all. Does this mean that there is not enough power? I think it can also mean that the os is not controlling it properly
Can anyone help me?
