Hi all, i'm having a problem when im running wireshark/tshark on Windows7 with e.g. tshark.exe -i \.\USBPcap1 everything is running fine, but the taskmanager show me a cpu usage of 100% for USBPCapCMD.exe the whole time the program is running. if i start the USBPCapCMD.exe seperately without the tshark it just takes 1-5% of the cpu usage at all. any tips/hints whats the difference between the call of tshark and usbpcapcmd.exe and how i can fix this ?! wireshark version is 2.2.7 64-bit, with included USBPcap Version asked 22 Jun '17, 03:32  itsbasti edited 22 Jun '17, 03:34 |
One Answer:
This is a consequence of extcap interface in USBPcap. See this issue. answered 22 Jun '17, 13:17  Pascal Quantin |
This seems to be a common problem. See also this question and the answer by sindy. You might try a recent automated version of Wireshark to see if there's any performance improvements over 2.2.7, and if so to report your findings.
