Antw: Re: udhcpc (1.12.1) - Problem with usb ?!

[Manuel Sahm]

Hello, sorry I will try to give you more detailed informations:
 
I have an Atmel AT91SAM9260 with an usb-host and usb device port.
 
I plug in my usb wlan stick in the usb host port. Then I establish a
connection to a router.
The ifplugd recognizes a connection. Then i start the udhcpc ( "udhcpc
--interface=wlan0 --now -s /etc/init.d/simple.script").
A valid ip address is available.
 
No I connect my host (PC) with the Atmel through the usb device port.
[I´m using gadgetfs]
Enumeration is successful. I want to use 2 Bulk endpoints for
receiving/sending data.
The problem is, that I can´t open /dev/ep1, which is the usb endpoint
for receiving data from the host.
ernno = Device or resource busy.
 
If i kill udhcpc all works fine ?
 
Thank you

Instead of adding --quit you need to look into the problem.

You insert what? Above you said you already detected the connection
using ifplugd. I'm confused. I'm also confused by "not abel to open the
EP1".
what is "EP1"?

Write up more coherent problem description.
