Problem to check if scanner is ready on startup? MFC C++

[keniff1]

hi forum,

we work on a mfc software to scan with an epson scanner…
everything works great, but we have on last problem:

On startup, when the scanner is booting, the scan process can´t be stopped. the process bar don´t start and it takes over 1 minute until an error message appears.
We think, the TWRC_FAILURE is thrown, but how can we check at beginn if the scanner is really ready? Its no problem when the scanner is switched off etc…
Has somebody an idea how to check it or even set the timer for the timeout smaller?
Greetings keniff
