Sleeping problems and crashes in 10.9

Since I upgraded to 10.9, it takes a long time before my Mac Pro goes to sleep when I select the "sleep" command in the finder menu. Sometimes, when the computer awakes, it hangs and it is a hard crash, because the only solution is to press the power button. I have never experienced this with 10.6-10.8.
My startup disk is an OWC SSD Mercury Extreme, I have never had problems with it, until now. 10.9.1 didn't solve the problem.
Booting under 10.6.8 under another disk doesn't give this problem.

 

Some additional info: I have a Calldigit USB3 eSata card installed. However, there are no sleeping problems under 10.6-10.8 with the drivers installed.

 

Problem still not solved under 10.9.1

I still have frequent hard crashes and it takes many seconds before my mac goes to sleep when I use the command "sleep". I reinstalled the Calldigit USB driver, it seems that the same driver is used under 10.8 and 10.9. The computer is rock stable when I choose a different startup disk with 10.6,7 or 8.

Please help.

 

I checked the logs but there are no crashes registered from the past ten days, although I had several fatal lockups. Strange.
I will try uninstalling the Calldigit driver

 

Uninstalling the driver doesn't solve the problem. Delays in sleeping and lockups remain. But only one time the logs says it is a crash:

I reset the SMC and the problem isn't solved.

 

I can't find com.taoeffect.ispy.kext even not by making invisible files visible.
I trashed some other files containing the word ispy

 

I deleted all ispy files (Espionage). The delay in sleeping when I choose the sleep command in the finder isn't solved. I unchecked wake up for network access in the Energy Saver Control Panel. Fingers crossed....

 

The Espionage files are all deleted.
I tried to startup in the safe mode, but it doens't work. After Apple logo appears, a rotating wheel keeps spinning. The desktop doens't appear.
