Compressed report descriptors for USB devices |
摘要 |
A method and apparatus for creating USB peripheral device report descriptors: A short, compressed, report descriptor is stored in a peripheral device. This short report descriptor is transmitted to a USB wireless bridge and combined with templates stored in the bridge to create a USP report descriptor. Power is saved because less time is required to transmit the short report descriptor than would be required to transmit a full USB report descriptor. Hardware is also saved in the peripheral device since less memory is required to store the short report descriptors as compared to storing a full USB report descriptor.
