strange problem print through com1

ok . this is going to be long explanation . my host is winxp while my client is also winxp .

I have a program that print through serial com to epson receipt printer (direct open the port and send message . no need install any printer driver). since I don't have a serial com on my notebook , I brought a usb to serial converter cable . the driver it self emulate serial com1 . because of that I can still use the program with making any changes on my notebook.

the problem occur when I try running my program on vbox client . I setup vbox enable serial com1 . when I run winxp client it detect the serial com 1 . when I run my program to print , it print but some message suppose to be printed gone . it seems like some of the message sending from client to host lose .

I confirm the problem is not with the converter cable . I test it to print nonstop 50 receipt without losing a single word in it.

how do I solve this problem.

If you want to print from the VM, why not attach the USB device directly? Enable USB, add a filter for the device and boot the VM. Now select the USB device from the Devices > USB menu item.

You did everything that was needed to attach the USB device to the Guest? So enabled USB, and added a filter AND attached it to the VM from the Devices menu?

on vbox usb filter , I see the usb device but the client winxp , not detecting the usb device . I try unplug and plugin while in the client winxp , nothing show up . I try run hardware wizard also nothing show up.

forget it . it solve when the host is linux (opensuse 11.1 64 bit) and the client winxp . on client winxp I plugin the cable and the hardware wizard detect it . after install the driver I try print and it come out perfect .

the only different between host linux and host winxp is I don't have the cable converter driver for linux 64bit while on host winxp I have and installed . is this cause the problem?

Having a driver or not should not cause a problem, but as it's not your everyday USB device, it might. I assume that you did the same on your Linux Host as you did on your Windows Host with the USB settings.
