@MarkRivers I don't modify handelSrc/Makefile. I downloaded zip file by browser. I will git clone dxp module from GitHub several days later, because the network of my computer doesn't work now. Thanks again.

@1458861693 downloading zip file is OK as long as you don't modify anything. I am pretty sure your problem is that you passed the CFLAGS argument to make, You should not do that because it replaced all of the other flags we need to use.

@MarkRivers , I have tried using make simply to build dxp on CentOS7, but it errors. And the output information note me to use C99. But Just now I build dxp master branch on Ubuntu20.04, it's no problem. I will test again on CentOS7 tomorrow.

Hi folks, I came across this issue as I had the exact same problem with a KETEK AXAS-M1 on a Debian 11 running as a VirtualBox guest under a Windows host. Maybe this is a similar configuration on your site(s). Compiling the EPICS dxp module (and KETEK installation with udev-rules) worked just fine. But running the microdxp IOC resulted in the error messages as shown above. In addition every time I started the IOC a kernel message showed up: 

dmesg 
usb 1-2: usbfs: process 2743 (dxpApp) did not claim interface 0 before use

The same kernel message and dxp_usb-error messages also appeared when starting a so-called xia_server for SPEC (certif) instrument control software, although this app runs fine and connects well to the KETEK on a "real" Debian on our instrument. Searching through the web brought me to your issue, but also to some VirtualBox forum post https://forums.virtualbox.org/viewtopic.php?t=68766. As a result, I changed the USB controller settings in VirtualBox from USB2 to USB3. Ét voilà: the xia_server and the EPICS dxp IOC work well. It seems that some guest OS do not implement well enough the USB 2.0 (EHCI). A change to USB 3.0 (xHCI) could therefore be an opportunity - it has helped me.
