Hi,
When I plug my USB, sometimes device node gets created while sometimes its not created. Following is a log showing such a non-creation scenario:
root: /> usb 1-1: new high speed USB device using musb_hdrc and address 4

While the USB connect output shows the entry sda1, there is no such entry in /dev. What could be the problem?
