你必须知道usb的设备名,然后用createfile打开
// strcpy(deviceName,"\\\\.\\HHusb-0");
//Get a handle to the device:
hDeviceHandle = CreateFile( deviceName,
GENERIC_WRITE | GENERIC_READ,
FILE_SHARE_WRITE | FILE_SHARE_READ,
NULL,
OPEN_EXISTING,
0,
NULL);
然后读写,要根据不同设备而定
DeviceIoControl(hDeviceHandle,
IOCTL_EZUSB_BULK_WRITE,
&bulkControl,
sizeof(BULK_TRANSFER_CONTROL),
hDataBuffer,
hDataLength,
count,
NULL )))
DeviceIoControl(hDeviceHandle,
IOCTL_EZUSB_BULK_READ,
&bulkControl,
sizeof(BULK_TRANSFER_CONTROL),
hDataBuffer,
hDataLength,
count,
NULL )))
// strcpy(deviceName,"\\\\.\\HHusb-0");
//Get a handle to the device:
hDeviceHandle = CreateFile( deviceName,
GENERIC_WRITE | GENERIC_READ,
FILE_SHARE_WRITE | FILE_SHARE_READ,
NULL,
OPEN_EXISTING,
0,
NULL);

DeviceIoControl(hDeviceHandle,

&bulkControl,
sizeof(BULK_TRANSFER_CONTROL),
hDataBuffer,

count,
NULL )))
DeviceIoControl(hDeviceHandle,
IOCTL_EZUSB_BULK_READ,
&bulkControl,
sizeof(BULK_TRANSFER_CONTROL),
hDataBuffer,
hDataLength,
count,
NULL )))
