Hi! I'm not an expert on this but from your attachments it seems the probe function of the driver fails.
The probe function of the driver is called whenever a new device is attached to the bus. For reference of the probe function see: http://www.lrr.in.tum.de/Par/arch/usb/usbdoc/node17.html Best regards Jan M.

Hi all, For a hobby project I'm writing firmware for a LPC214x (ARM7) microcontroller to implement a simple serial-over-USB port. I think I have the basics covered and the device appears to work under windows, however under linux I'm seeing a "Generic device with no bulk out, not allowed." message. The usbserial eventually does create a /dev/ttyUSB0 file. Is it normal to see the message mentioned above? Or is there anything wrong with the configuration of my device? Or perhaps there is something wrong with the linux kernel driver? I tried to conform to the USB CDC specs. My device has two interfaces, a communication class interface with an interrupt-in endpoint and a data class interface with two bulk (in and out) endpoints. I'm attaching the syslog, dmesg and lsusb -v output.
