Hi, I'm trying to establish a connection between a Windows XP host and a Linux (PXA-270) client over usb using the gadget_serial driver.
I started with the pxa27x_udc driver of Rodolfo Giometti (http://wiki.enneenne.com/index.php/PXA27x_UDC), configured and compiled the neccessary kernel modules (linux kernel 2.6.22). As describted in /Documentation/usb/gadget_serial.txt i'm able to establish a connection between a Linux host and a Linux client (PXA-270) using ACM mode (use_acm=1). The problem starts when i'm trying to establish a connection with a Windows XP (and at least Windows 2000 too). As expected Windows recognises a "Gadget Serial" device and a COM Port is added in the Hardware Manager. On the client (PXA-270) side i get following "dmesg" entry "gs_set_config: Gadget Serial configured, full speed CDC-ACM config". But when i try to open a connection to the COM Port (on the Windows XP) with putty (or HyperTerminal) an error like "unable to open COM Port" occurs. So my questions: 1. Has anybody else already tried to get a serial connection from Windows XP to Linux on a PXA-270 platform over USB working? 2. Are there known issues with a serial connection over USB to a Windows host on other platforms? Any hint will be welcome Regards, Aurel - To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
