9860GII Power Graphic 2 transfer problem with using xfer9860

[hhacker Profile]

hi everyone,
I just bought my third calculator which 9860 GII Graphic 2,and I got some weird problem here.
My upload program can transfer certain files to 9860(based on Casio fx-9860G communication utility,aka xfer9860),which is works fine on 9750 GII,9860 slim and 9860 GII SD.
But this new GII Graphic 2 cannot response my command anyway,I used BusHound to capture communicate info,it seems like connection works fine but any OUT command I sent to Endpoint 1 just got no response error,it makes me confused.
Please give me some advice about how to solve this problem.
Thanks for your time.

btw,fa-124 works fine with Graphic 2,I captured its communications(just few lines capture info when connection was established):

xfer9860 does not work well with GII models.
But PierrotLL found a solution for it work with GII models:

To adapt xfer9860 for fx9860gII, I know you have to change the constant T_POSITIVE (Casio9860.h line 70). 0x06 is the value for first fx9860, on the new ones it's 0x05.
To accept the two values, you may change function fx_doConnVer (Casio9860.c line 131).

I dont know if this changes also work with Power Graphic 2, but you can test and give your feedback.

I already wrote a bug fix for GII,but it's not work for graphic 2.
After connection established,Any OUT command will receive no response error,when I try this again,It just show a STALL PID error.
I guess after CLEAR FEATURE finished,maybe I need set Endpoint 0 to STALL manually,also set endpoint 1&2 to VALID.But it seems like libusb did not offer a function to do these things.

I can not help much more since I do not use linux and i dont own a Power Graphic 2.

Some offtopic: Have you tested the screenstreamer? (If yes, you could use it with a GII calc?)

Thanks for your help.
Compare with 9860GII,Graphic 2 's OS version was upgrade to 02.02.0201,It's just a little rise.
Since Graphic 2 changed it's cpu to SH4A,maybe it has some hardware difference.
...sigh,Maybe debug FA-124 is my only choice,but it's too waste time.

I'll trying to move on libusb 1.0,hope it works.

libusb1.0 with WinUSB driver is worked,everything looks fine now.

Could you send me your version? I cant get my hacked 9750GII to communicate with xfer...

OK,I'll post it here,the key frame is you need waiting for calculator to response 0x6 when you send something in.
I have changed it in usbio.c:

Code: Select all

int ReadUSB(struct libusb_device_handle *usb_handle, char *buffer, int length) {
   int ret = 0;
   int BytesRead = 0 ;

   ret = libusb_bulk_transfer(usb_handle,0x82,buffer,length, &BytesRead,USB_READ_TIMEOUT);
   if (fx_getPacketType(buffer) != T_POSITIVE) {
       ret = libusb_bulk_transfer(usb_handle,0x82,buffer,length, &BytesRead,USB_READ_TIMEOUT);
    }

   if (ret < 0) { printf("ERR: ReadUSB(): Could not read: %i\n", ret); }
   debug(1, buffer, ret);
   return ret;
}

When I got positive reponse,i just read it again,everthing is ok.The only porblem is it will slow down my graphic2's transfer speed a little(but can ignored).

My past code use libusb_win32's driver as a fillter,it seems did not compatible with my 9860 Graphic2 cal,so I change it to libusb 1.0 with WinUSB driver,I did not go back to libusb0.1 and test it for linux,but it should be ok if your cal is not graphic2.

There is a download link in my blog,be noticed,my program's main function is upload a few certain files to casio 9860 cal.
I did not change most of xfer9860 code but upgrade it to libusb 1.0 library(api name is different),and I didn't clean up my code yet,so it has some useless comment code.

I can't build that code...


I changed line 70 in Casio9860.h to:

Code: Select all

#define T_POSITIVE   0x05


The I edited usbio.c to look like this:
