F5U103 unable to open card reader

you might need a new usb cable, or you may need to have the reader checked or the computer checked

Problem is that the Bernina software you are using expects to talk to a 'COM port and the PC's USB serial interface doesn't automatically default to a COM port. Make sure you have installed the software that was delivered with your USB-to-Serial adapter and look on your PC's 'Device Manager' under 'Ports' - you should see the USB adapter listed and it should be assigned to a COM Port number. You need to check what COM port numbers are accepted by the Bernina embroidery software (sorry, I cant remember and haven't got one here presently) - it should be in the Options menu. You have to ensure that the USB 'virtual COM port' is the same as that which is set in the Bernina software. If the Bernina software doesn't support the COM port allocated to the USB interface, go to 'Properties, Port settings, Advanced, COM port number and set this to the same as the COM port number in the Bernina software - hopefully this should set up the link OK, provided you haven't got a COM port clash - to avoid this, it's usually best to choose a COM port number of 2 or above.

Hi, I have the same problem with mine. Janome have not been very helpful. I didn't know if it was the card or the card reader/writer. I have a Janome CX500. Have you solved any of the problems?

check the com port of the appliaction, it is based on com1 only then you will need to make changes to the com4 to com1 follow these steps
open device manager
choose com4 and then right click for properties
choose port settings
choose advance
change the port number from 4 to 1
that will be all you can now give it a shot again

Contact Janome helpline who can guide you through this. The phone no may be on your machine or else in the manual.http://janome.com/

You can buy a USB-Serial Adapter at Best Buy for $36. Or, if you want to save money and spend only (roughly) $10, you can buy one on eBay.

They do make them, still, and you can still get them at most computer supply stores.

Hope this helps!!

In this FAQ list (from PFAFF web) you find 100 times the same question and answer:
H402 My new computer does not have any serial COM ports, so how does it communicate with my Pfaff creative 7570?

You will need to obtain a USB Serial Adapter, which adds a serial port to your computer by plugging it into a USB port. Suitable adapters can be obtained from Belkin [http://www.belkin.com] and Keyspan [http://www.keyspan.com].
The following USB Serial Adapters are known to work with the Pfaff creative 7570:
• Belkin F5U103
• Keyspan USA-19QW
Please note that the Belkin F5U109 is listed as working with the Pfaff creative 2140/2144 (FAQ #H405), but it does not work the Pfaff creative 7570.

Dear Dawn528,

The driver is included with your PSW software and will load automatically when you install the software.

You will need a serial/usb adapter to connect from the machine serial port to your laptop usb port. This will come with a seperate driver that you nee to install.

Good luck

Buy a USB to Serial Adapter. I bought one made by IOGEAR and have had not problems,
