- Modification history
- --------------------
- 01d,26jan00,rcb Modify usbRecurringTime() to accept <bandwidth> instead
- of <bytesPerFrame>.
- Add usbDescrCopy32() and usbDescrStrCopy32().
- 01c,17jan99,rcb Add usbConfigDescrGet() function.
- 01b,23nov99,rcb Add usbRecurringTime() function.
- 01a,16jul99,rcb First.
