Today i was reading kernel log and found this lines

[60828.442095] usb 1-1: USB disconnect, device number 2
[60831.001390] usb 1-1: new high-speed USB device number 3 using ehci-platform
[60831.154613] usb-storage 1-1:1.0: USB Mass Storage device detected
[60831.162350] scsi host1: usb-storage 1-1:1.0

Does my USB work in USB1.1/1.0 mode and not USB2.0 mode?

Also i found these lines. Is this bad? Are these bad sectors or what?

[61030.708800] blk_update_request: I/O error, dev mtdblock0, sector 24

mtdblock0 errors indicates that the flash (nand) driver has issues or the flash chip itself. It's not related to USB.

This has nothing to do with USB1.1 / USB2.0, but is the place of the device in the USB chain.

EHCI is telling you the speed.
