host.uvproj missed tusbh_cdc_*.c in source list

hi, I found MDK-ARM project inside demo/host folder failed to compile.
maybe you forgot to add tusbh_cdc_acm.c and tusbh_cdc_rdnis.c into usb_host group.

[xtoolbox]

I'll check it, the mdk project file is not fully tested

[banxian]

in retarget.c the compiler define should be "#if !defined ( __CC_ARM )"
because if enanble gnu in keil mdk, then __gnu_c got defined.

I tried port an dfu-util based checkm8 to F723edisco with teenyusb stack.
I make a copy of usbh_hid.c to usbh_dfu.c and removed unused codes,
then link new command "check" to
void cmd_check(char* argv[], int argc)
{
tusbh_interface_t* cdc = 0;
if (fs) {
cdc = find_dfu(((tusbh_root_hub_t*)fs->user_data)->children[0]);
}

if (!cdc && hs) {
    cdc = find_dfu(((tusbh_root_hub_t*)hs->user_data)->children[0]);
}

if (!cdc) {
    printf("No DFU interface attached\n");
}

int r = tusbh_dfu_dnload(cdc, (void*)Zero800, 0x800, 0x800);
printf("Send dnload result = %d\n", r);
if (r < 0)return;
printf("\n");

}
enum and find is working well,
but strange error occurred when test device with an 0x800 empty download packet.
In nxp's imxrt1010 evk I can do it and verify though packet sniffer, 32 data followed by setup packet.
in teenyusb the data packet is sent only 2 times if I recalled correctly
I don't know if it should be a issue, I think the ep0 control points shares same code between data points, and just working fine in descriptor / serial query
