[pyusb-users] Trying to write to OUT EP Bulk on Win10

[Igor Bezenchuk]

I am Interested in generating random bulk traffic with libusb and pyusb to different bulk devices(i.e Flash drives etc...) ep buffers and check data integrity.I used this code:import usb.core# I used Gensys usb to sd card readerdev = usb.core.find(idVendor=0x05E3 , idProduct=0x0746)if dev is None: raise ValueError('Device not found')for cfg in dev: for i in cfg: for e in i: print e.bmAttributes print e.bEndpointAddress print "" #if you find OUT EP if(e.bEndpointAddress == 2): e.write(0x00) e.write(0x01) and I got this error:"raise NotImplementedError(_strerror(ret))NotImplementedError: Operation not supported or unimplemented on this platform"pyusb does enumerate device and it's endpoints correctly but it fails to write to them.as I saw in other posts this issue is well known in windows, my question is there any way to go around this to write to device's EP in Windows without installing custom driver with Zadig?

and I got this error:"raise NotImplementedError(_strerror(ret))NotImplementedError: Operation not supported or unimplemented on this platform"
pyusb does enumerate device and it's endpoints correctly but it fails to write to them.as I saw in other posts this issue is well known in windows, my question is there any way to go around this to write to device's EP in Windows without installing custom driver with Zadig?

No way under Windows. There is no generic USB driver attaching to
all USB device.

I read at libusb maling list about usbdk which, from its description, should allow to attach and detach device drivers under windows. Did you hear about it? can it be combined with pyusb?

Yes. It should be okay to work with pyusb.

On the other hand, you need to install usbdk on the computer. There is
no Inbox Windows driver which can do the things you want. And I consider
usbdk to be a custom driver as well.

Hi,

I think you may find the answer for your question in libusb mailing list.
