FT4222設備信息在Windows下正確，在Linux下不正確？

我正在嘗試使用libft4222與FT4222芯片進行通信。當我運行由FTDI提供的以下示例代碼時，我在Windows和Linux平臺之間收到不同的響應。FT4222設備信息在Windows下正確，在Linux下不正確？

示例代碼：

FT_STATUS ftStatus; 
FT_DEVICE_LIST_INFO_NODE *devInfo; 
DWORD numDevs; 
// create the device information list 
ftStatus = FT_CreateDeviceInfoList(&numDevs); 
if (ftStatus == FT_OK) { 
    printf("Number of devices is %d\n",numDevs); 
} 
if (numDevs > 0) { 
    // allocate storage for list based on numDevs 
    devInfo = 
    (FT_DEVICE_LIST_INFO_NODE*)malloc(sizeof(FT_DEVICE_LIST_INFO_NODE)*numDevs); 
    // get the device information list 
    ftStatus = FT_GetDeviceInfoList(devInfo,&numDevs); 
    if (ftStatus == FT_OK) { 
     for (int i = 0; i < numDevs; i++) { 
      printf("Dev %d:\n",i); 
      printf(" Flags=0x%x\n",devInfo[i].Flags); 
      printf(" Type=0x%x\n",devInfo[i].Type); 
      printf(" ID=0x%x\n",devInfo[i].ID); 
      printf(" LocId=0x%x\n",devInfo[i].LocId); 
      printf(" SerialNumber=%s\n",devInfo[i].SerialNumber); 
      printf(" Description=%s\n",devInfo[i].Description); 
      printf(" ftHandle=0x%x\n",devInfo[i].ftHandle); 
     } 
    } 
}

在Windows上，我收到下面的輸出，這看起來是正確的：

Dev 0: 
Flags= 0x2, (CLOSE-HS) 
Type= 0xa 
ID= 0x403601c 
LocId= 0x1131 
SerialNumber= A 
Description= FT4222 A 
ftHandle= 0x0 
Dev 1: 
Flags= 0x0, (CLOSE-FS) 
Type= 0xa 
ID= 0x403601c 
LocId= 0x1132 
SerialNumber= B 
Description= FT4222 B 
ftHandle= 0x0

在Linux（64位Ubuntu的，運行libft4222的i386的版本，我的測試應用程序）我收到以下輸出，看起來不正確：

Dev 0: 
Flags= 0x1, (OPEN-FS) 
Type= 0x3 
ID= 0x0 
LocId= 0x0 
SerialNumber= 
Description= 
ftHandle= 0x0 
Dev 1: 
Flags= 0x1, (OPEN-FS) 
Type= 0x3 
ID= 0x0 
LocId= 0x0 
SerialNumber= 
Description= 
ftHandle= 0x0

我很好奇爲什麼系統之間的區別？爲什麼一個顯示爲關閉而另一個顯示爲打開？

那麼'lsusb'說什麼？ – Olaf

您添加C++標記的任何原因？快速一瞥，代碼看起來像是純粹的C.你使用C或C++編譯器嗎？ – Olaf
