Hi, I am looking to attach a USB thumb drive for external storage to the overo with a palo43 board. When plugging in the USB, I get this message: usb 1-1: new high speed USB device using musb_hdrc2 usb 1-1: New USB device found, idVendor=0951, idProduct=160f usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 (device name etc.) usb 1-1: rejected 1 configuration due to insufficient available bus power usb 1-1: no configuration chosen from 1 choice To solve this, 5V dedicated power supply was given to the USB. However, the same problem persists. Are USB drives supposed to be configured automatically? I feel like I'm missing something because it seems difficult to set up this type of storage.

For anyone with the same problem when plugging in a USB ("rejected 1 configuration due to insufficient available bus power") the problem has been solved. The issue may have occurred with a specific line of USB drives. However, it is unclear whether the 5V of power supplied to initially attempt to fix the issue is necessary. $ echo -n "bconfigvalue" >/sys/bus/usb/devices/"usb address"/bConfigurationValue Example: $ echo -n 1 >/sys/bus/usb/devices/1-1/bConfigurationValue This successfully mounted the drive under /media/sda1.
