Catalyst 2960-CX - Can't detect USB drive

[HeKay]

Hi,

I'm trying to load a config file from a USB drive.
When I try to connect the USB Stick with the 2960 switch I get the following error:

%USB_HOST_STACK-5-USB_ENUM_FAIL_GETDESCR: Failed to enumerate a USB device as not able to read the device's description.

I've tried reformatting the drive multiple times (FAT32, NTFS both don't work) and I couldn't find any Information regarding this error.

Get a different brand of USB flash drive.

Hi @Leo Laohoo ,

I've tried using a different brand, with no luck. The same drive works perfectly fine on a 9200 Switch.

Hi @Julio E. Moisa ,

I can't access this command, since the switch won't really detect the drive at all. The moment i plug the stick into the switch, i get the error mentioned above.

Hello @HeKay,

As concerned FAT16 (<4Gb) was Ok on this Cisco SW model.

Hello M02@rt37 ,

I've just tried formatting the drive as FAT16, which doesn't work either. I get the same error.

I've also tried previously using the same Stick on a 9200 Switch, which was instantly detected and worked perfectly fine. So the drive itself works well.

Best regards

[M02@rt37]

Ok @HeKay,

same USB on an other C2960 but an other IOS version ? Do you have that?

[HeKay]

Unfortunately not. I can't upgrade the version either, since the Switch won't accept any drives

[HeKay]

Further Update:

I've tried another drive from a different brand, formatted it to both FAT32 and FAT16 and both times i got the following error:

May 4 13:42:15.532: %USB_HOST_STACK-3-USB_FLASH_READY_TEST_FAILED: USB flash failed to pass 'Ready' test.
May 4 13:42:15.532: %USBFLASH-3-DEVSTARTSTOP: usbflash0 MSCD_StartStop failure in usbflash_mscd_scsi_listener!

Could it be possible that the Switch won't accept any drives above USB 2.0?

[M02@rt37]

Yes @HeKay, it's possible ! You can test with a good one ?

This means the USB flash is of a different "type".  

Try a different brand and a different size.

[UnspokenDrop7]

This was probably the solution for me - switching from a "brand new" USB flash to an "older" one. I do not know exactly what USB version the two flashes I used had.

Maybe you could set this post as the solution?Just to make it even easier for others (including me) in the future.

Thanks!
