We are using a vendor-provided SDK to access their hardware through EA framework and intermittently the EA framework streams stop working (in particular, the input stream reports 0 for hasAvailableBytes). In some cases, this situation persists until we detach the device and reattach (this is via a lightning connector).
After installing the IAPD debug profile and retrieving logs, we notice a few interesting log entries from the syslog we retrieve off the tablet.
I am trying to understand and make sense of this and determine how this can be fixed. Anyone have a clue?
