Attached is a rather long log, which is reduced to "host 7400" and there only the last part from the last

BEGIN_TRANSATCTION:

SCARD_IOCTL_BEGINTRANSACTION, completionID=0000120f, ioStatus=00000000

to the last Transmit (when the channel dies)

It ends with:

ScRedirVvc_DumpMsg():1053: Entry
72 44 Header->RDPDR_CTYP_CORE = 0x4472
43 49 Header->PAKID_CORE_DEVICE_IOCOMPLETION = 0x4943
ScRedirVvc_DumpMsg():1096: Exit
ERROR(c0000023) | 7400|: Incorrect IO completion status
ScRedirVvc_ParseIOCompletion():1473: Exit
ERROR(c0000001) | 7400|: Failed to parse IO completion message

But there is no dump from the failed completion message, which is the interesting part.

ScRedirVvc_RedirectScResponse():2025: Exit
ERROR(c0000001) | 7400|: Failed to redirect SC IO completion packet
ScRedirVvc_HandleRequests():2159: Exit
