Doing some USB host mass storage testing with our USB stick for production on the SCM20260D. The example code: USB Host throws a exception when attempting to init the USB stick.
I have tried other USB sticks form different manufactur and succeeded so the code works but is picky about the USB stick used.
Is there other requirements for the USB stick then FAT16 or FAT32 for it to be compatible?
FAT16 and FAT32 are supported.
Does sitcore detect it as a storage device? Looked like it but then it fails to mount!
If you want to ship that memory stick we can investigate.
Yes the sitecore detect our USB stick as storage device(case BaseDevice.DeviceType.MassStorage )
Where should i ship it to?
Send us simple code that you can reproduce the issue, and show us what kind of USB you are using.

not sure how to identify what USB stick we’re using as it is a no brand device
var usbReady = false;
var usbHostController = UsbHostController.GetDefault();
usbHostController.OnConnectionChangedEvent +=(a, b) => { usbReady = b.DeviceStatus == DeviceConnectionStatus.Connected; };
usbHostController.Enable();
while (usbReady == false)
{
Debug.WriteLine("Waiting for connect ready!");
Thread.Sleep(1000);
}
var sc = StorageController.FromName(SC20260.StorageController.UsbHostMassStorage);
IDriveProvider drive = GHIElectronics.TinyCLR.IO.FileSystem.Mount(sc.Hdc);
Hey
I have now attempted your suggestion without any luck. when I insert the USB stick it throws the exception.
Is it failed on that one only or other ones?
Is there any way we can have that one to investigate?
I have tested 3 with same result.
please let me know the shipping info and we will send some.
Thank you for sharing the USB.
I guess the address is on our website, but you can contact to our support: support@ghielectronics.com
They take care shipping better than me.
Just tell them that you need to send your usb thumbdrives to GHI for investigating.
Thanks a lot.
Did you ship your usb yet, please?
Yes they should be shipped yesterday or today.
Thanks. Curious about this usb.
Hi,
We tested your thumb drives and able to reproduce issues.
The fixed is available in next release. For now, if you don’t want to wait, you need find a way to format these usb drives with “full size”. We found and tested the first method (diskpart) from this link below and get it work:
