Hello, I can use it on Win7. However, it did not fully debugged.

MSC is required for SD memory.

main.c: SDFileSystem sd(p5, p6, p7, p8, "sd");

And, CDC is required for .inf file.

Thank you Suga ! (I don't know why I don't receive alerts when a reply it's posted).

I have managed to make it work , however it seems to be not so stable. I am having problems especially with serial port.

Do you have any updates on serial port emulation ?

Kind Regards, DAniel

Hello Daniel,

As you say, this program is not stable. It is difficult for me to fix...

Hi,

I have connected BlueTooth USB device to my mbed (BlueUSB). Now I´m looking for a solution to transmit a file from SD card via bluetooth to other device. Do you have an idea how to proceed ? Any hints ?

Br, Mika

I am afraid that your question it's a subject for other topic. however if your file it's text it should be fair easy to retransmit it.

Suga, Daniel, how did you get it to work in win7? All I have is a blue screen after connecting it to win7 64bit?!

On WinXP, it installs serial port, but after opening it with hyper terminal, it doesn't receive or transmit. It doesn't install any drives.

If I connect it to the picture frame (USB Linux host), usb drive works... I'm really frustrated by now...

I'm f*king with it for a days now, with no result...

When compiling I get this error.

"statement is unreachable" in file "ChaNFS/CHAN_FS/ff.c", Line: 1649, Col: 11

If this is a composite device, why isn't it using usbccgp.sys and composite device enumeration like mbed interface chip?

I still cannot get it to work... Please help!

Now I get the mass storage, but serial isn't working... :(

It really works. The point is to uninstall any previous driver and to modify serial.inf...

Here is the serial_msd.inf

Hello Goran, Thank you for updates. Mass storage was generally working for me too. I will try this version of inf file ! (I still don't understand why I receive the alerts so late). Kind REgards, DAniel

I all The first time I install the cdc driver it works. But, as soon I cancel the virtual disk verification in windows, the virtual port com doesn't work any more. In this case, the MBED receive char from the PC, but when I try to send a char from the MBED (cdcmsc.putc(c);), the USBDevice::write(...) function block the program and I receive nothing.

Thanks for your help
