When a USB device is enumerated it will report one or more endpoint
descriptors which contains a bInterval field which specifies the
interval a host should periodically poll for that particular endpoint
when scheduling transfers. But the units this value is expressed in
(in whole ms, a power of 2 x 1ms, or a power of 2 x 125us) may differ
depending on the speed of the device and whether the endpoint is
isochronous or interrupt.
Some high/super-speed devices, which are supposed to report isoc/int
bInterval as a power of 2 x 125us, incorrectly report full-speed
bInterval values (that is, in whole units of ms) in their interrupt
endpoint descriptors which results in an assertion error due to being
out of range of the spec-expected values. Rather than asserting, try
to adjust those assuming they were expressed in units of ms with an
upper limit of 128ms.
