1. getVendorId() should give you manufacturer's name. Other calls include getDeviceName(), getDeviceId(), getDeviceClass(), getDeviceSubclass(), getDeviceProtocol(), getProductId(). refer this link: Android USB Host

2. For Data Transfers, refer this link: BulkTransfer. Read from the file in a buffer and pass the buffer to bulkTransfer call along with specific output Endpoint of your device and data length.
