I've owned my K150 programmer for several weeks now. It has been running OK on VISTA (eeecccchhhhhh!!!) for the few weeks I've owned it. One thing I've noticed is that every time I plug into the USB port, it gets a new serial port  COM # assigned to it, in ascending order. No big deal, I go to "serial port change" and enter the new number and it works- until now.... When I tried to use my programmer today it was assigned COM 10 but the "serial port change" function does not seem to allow a double digit COM port assignment. No big deal I thought, I'll just delete the FT232BM driver, reboot the computer plug in the programmer and reinstall the driver- WRONG!!! After I reinstalled the FT232BM driver the programmer was assigned to COM 13. It now seems I'm really screwed. I took a look at other posts  but didn't find any references to this problem or I would have tried them before I started crying in the forum. Am I the only one who has experience with this? Where do I go from here? How do roll the COM port number back? Thanks in advance.....

Edit:  well, I jumped in too quickly on this.  I saw "programmer" but was thinking "adapter" when first replying, probably because of the subject line.  These instructions are for an actual USB-serial adapter.  I haven't used my K149 through USB, so am not sure if this applies to a USB programmer.  In principle the USB connection on the programmer is doing the same thing.  I'll leave the instructions here, just in case.

===================================
This is in XP, but is similar for Vista.
With the device connected...
- Open Device Manager (right-click MyComputer, go: Properties | Hardware | Device Manager)
- Expand the "Ports (COM & LPT)" section, the device should appear in the list
- Right-click on the device, go: Properties | Port Settings
- Click on the "Advanced" button
    Beneath the Buffers section, you should see a place to select the Com port number.  
    The list goes from 1 to 255 on my system, with already-in-use ports marked.

Doubly wrong!!!

You must install the FTDI driver first before plugging in the programmer. Refer to the installation instructions from the FTDI website.

Make sure you completely remove the current driver before installing the new one.

I think I have the same problem too. The COM port number available in my laptop is double digit (23,15,16,etc.) so I couldn't enter my COM port number in microbrn.exe

When I try to do as what John have said (change manually the number) it still didn't work.
please help me, thank you

I am running Windows 7. I am able to change the COM port number as follows:

1. Click on 'Start' button then right click on 'Computer'. Select 'Properties'
2. Click on 'Device Manager'
3. Click on 'Ports'
4. The USB serial port will be listed there - double click on it (or right click and select Properties)
5. Click on the 'Port Settings' tab then 'Advanced'
6. At the top of the windows is a drop down box that allows you to select the COM port number to assign. Select the COM port you want then keep clicking OK to get out.

All versions of Windows will allow changing the COM port but the procedure may be slightly different.

I have succesfully changed the port number (in my case I changed number 23 to number 2).
But when I try to enter port number 2 in microbrn.exe, "there appears to be problem accessing the COM port" error window still appear..

Most PCs have two serial ports - COM 1 & 2. Try setting to COM port 5 and try again.

I assume you have installed the FTDI USB driver?
