现在很多设备是有USB接口可以读U盘 插上读卡只也可以读各种卡，但是如果我的设备只有TF或SD卡我需要转换成USB母头这样可以插USB接口的设备。 求解决方案（报酬可议）

嗨支持我购买了32Gb Optane M.2内存模块。我转换为GPT，安装RST，禁用CSM，在主驱动器末端至少制作了5MB的未分配空间。我在Bios中将M.2端口重新映射到RST，并且该模块在BIOS / UEFI中显示在RST下，但在RST中的“intel Optane Memory”选项卡下，它表示“您的系统似乎是英特尔的内存准备就绪但计算机中未检测到英特尔操作内存模块。请安装兼容模块“。MB：Asrock Z370 Extreme使用M.2_1CPU：i5-8600k硬盘：WD 3TB请帮我...谢谢キャプチャ3.PNG 124.8 K.IMG_20180916_192302.jpg 763.7 K.IMG_20180916_192253.jpg 861.3 K.IMG_20180916_192138.jpg 752.6 K.IMG_20180916_192113.jpg 844.6 K.以上来自于谷歌翻译以下为原文Hi Support I have purchased a 32Gb Optane M.2 memory module.

我们有一个问题，一个更大的（4096字节）转移到EP0。在Windows 8和超高速，这种转移是失速控制转移。较小（64字节）传送功。和4096字节传输似乎是工作在高速模式的USB2.0端口。捕捉厂商请求处理在转让这个尺寸的正确方法是什么？下面的工作是什么？CYU3PUBGETEP0DATA（4096，计数，和ADCOUNT）；因为EP0大小设置为64字节，但整个传输更大，什么时候u***setup事件被称为？这是可能的，数据的酮基部分由每次调用getep0data收到，因此需要多个电话？ 以上来自于百度翻译 以下为原文We have an issue with a larger (4096 byte) transfer to EP0.On Windows 8 with SuperSpeed, this transfer is stalling the control transfer.Smaller (64 byte) transfers work.And the 4096-byte transfer seems to be working in High Speed mode on USB 2.0 ports. What is the proper way to capture a transfer of this size within the vendor request processing? Will the following work? CyU3PU***GetEP0Data(4096, count, &readCount); Since EP0 size is set to 64 bytes, but the entire transfer is much larger, when does the USB setup event get called?Is it likely that onyl part of the data is received by each call to GetEP0Data, thus requiring multiple calls?

大家好！在CyPress FX3上成功完成了YUV格式数据UVC批量模式的传输，通过打印每秒DMABUF计数，测试了数据传输速度，最大可达200 Mb/s。ARG:最大突发大小＝16DMABUF大小＝16×1024DMABUF计数＝10然而，帧速率与理论值相差甚远，我用初次捕获法观察帧速率，当分辨率为2592x1944时，帧速率最高可达10fPS，即PC的实际速度小于100Mb/s。然后，我改变了ARGSTO测试，当DMABUF大小＝6×102时。4，速度约为100Mb/s，分辨率为2592x1944时帧速可达10fPS。即使当DMA BUF大小＝32×1024，DMA BUF计数＝5时，当分辨率为2592x1944时，FrAMATETE仍然是10FPS，但是数据传输速度可以达到250Mb/s。所以我猜PC机处理UVC数据的速度太低了！也许它受到UVC驱动程序或解码器的限制，或者别的什么东西！最后，我想通过使用批量流协议来提高速度，但是失败了！（它可以启动多个DMA信道来传输数据，但是速度总是在7Mb/s左右，数据大小总是在1024B），我参考了FX3SDK中的CyfxBulkFipe，我不知道UVC批量模式是否能够支持流协议！能告诉我答案吗？谢谢！对不起，我的错误和表达不清楚！ 以上来自于百度翻译 以下为原文hello！everybody ！I successfully finishedtransfering YUV -format data in UVC BULK mode on cypress FX3，I tested the data transfering speed by printing the DMA buf counts per second ，and it almostlyreach to 200MB/S more. args：max burst size= 16 DMA BUF size = 16*1024 DMA BUF counts = 10 however，the frame rate is far away from the theoretical value，I watched the frame rate using debut capture，and framerate is at most up to 10fps when the resolution is 2592x1944， namely，the actual speed at PC is less than 100MB/S.then I changed the args to test，and when DMA BUF size = 6*1024，the speed is about 100MB/S，and framerate can be up to 10fps when the resolution is 2592x1944.even when the DMA BUF size = 32*1024, DMA BUF counts = 5 ,framerate is still10fps when the resolution is 2592x1944.butthedata transfering speed can be up to 250MB/S . so Iguess that the speed of PC processing UVC data is too low!Maybe it's restricted by UVC driver or decoder or something else! at last, I wanna improve the speed by using BULK stream protocol,but it failed ! (it can start the mulitiple DMA channels to transfer datas,but the speed is always about 7MB/S,and the data size every times is always 1024B) I referred the examplecyfxbulkstreams in FX3 SDK, I dont know whether UVC bulk mode can support the stream protocol!can anyone tell me the answer? thx! and sorry for my mistakes and unclear expressiong!

你好，我正在开发一个USB复合设备，提供两个功能：-从USB设备到USB主机的数据流。一个USB接口，一个大容量端点-一个用于控制设备的虚拟COM端口：CDC类设备，当我只在超高速配置设备中安装流接口时，一切都正常。端点同伴中设置的突发大小被适当地设置，并且我能够处理由设备发送的视频流的吞吐量。当我把两种配置都放在超速配置设备中之后，在定制.INF文件之后，两种设备都会出现在Windows（流媒体设备+串口）上，但我不再能够处理视频流。打印视频流端点SSMax Surb参数表明，SSMultSurb不再设置为15，而是0，好像超高速端点同伴在此情况下被忽略（注意我正在处理Wi7）。在Linux中卸载USB描述符（LSUB-V）表明，在这两种情况下，最大突发大小被设置为15。有人已经面对这个问题了吗？如何修复？我附上USB描述符以供参考。当做，雅恩CYFXVCDC.C.ZIP2.8 K 以上来自于百度翻译 以下为原文Hello, I'm developping a USB composite device that provides two functionnalities: - Data streaming from USB device to USB host.: one USB interface, one bulk endpoint- A virtual COM port for controling the device : CDC class device, When I put only the streaming interface in the superspeed configuration device, all is OK.The burst size set in the endpoint companion is properly set and I am able to handle the throughput of the video stream sent by the device. When I put both configurations in the superspeed configuration device, after customization of .inf files,both devices are seen on windows (streaming device + serial port), but I am no longer able to handle the video stream. Printing the video stream endpoint ssmaxburst parameter shows that the ssmaxburst is no longer set to 15 but to 0, as if the superspeed endpoint companion has been ignored in this case (note that I am working on Win7). Dumping the u*** descriptors in linux (lsu*** -v) shows that in both cases, the max burst size is set to 15. Did someone already faced that issue ? How to fix it ? I attached the u*** descriptors for reference. Regards,Yann cyfxuvcdscr.c.zip 2.8 K

你好，我试图在Windows 7, 64位OS上安装FX3.0的驱动程序，但我失败了。基于CysB.PDF，我必须使用“X64”文件夹，但是，在Wi7（X86）下没有这样的文件夹。有没有Wi7 x64的驱动程序？谢谢，纳西拉 以上来自于百度翻译 以下为原文Hi, I am trying to install the driver for the FX3.0 on windows 7, 64-bit os, but I am unsuccessful. Based on the CyUSB.pdf, I have to use the "x64" folder, however, there is no such a folder under win7 (only x86). Is there any driver for win7 x64? Thanks, Nazila

好的，这是一个奇怪的例子，但是我们看到它发生了两次，MPLAB 3.51和3.55。我们最初安装了MPLAB 3.51，安装在Windows 7, 64位机上，运行良好，使用IPE编程使用PICTIT3的PIC16设备。然后有一天，安装了SaleaLogic 16协议分析仪装置。在安装了驱动程序之后，当MPLAB-X IPE启动时，它的窗口要么完全是空白的，要么是被绘制出来的，但它只是冻结了。它的右上角说“校验和”只是说“计算”。MPLAB-X IDE仍然运行正常，所以我们使用它来编程设备。我们试图卸载3.51并重新安装。运气不好，3.55岁的时候我们试着安装。没有运气。我们在另一台电脑上安装了3.51台，并验证了它在第一台计算机上的运行。然后我们安装了SALEAE分析仪。IPE又坏了。安装了3.55个IPE仍然被打破。这是一个有趣的地方：IPE 3.40：工作非常好。所以，有人对这件事有什么想法吗？ 以上来自于百度翻译 以下为原文 OK, this is a weird one, but we've seen it happen twice, with MPLAB 3.51 and 3.55. We initially had MPLAB 3.51 installed on a Windows 7, 64-bit machine, running just fine, and using IPE to program some PIC16 devices using a PICKIT3 just fine. Then one day a Saleae Logic 16 Protocol Analyzer device was installed. After the driver for that was installed, when MPLAB-X IPE was started, the window for it was either completely blank, or it got drawn, but it just froze. The upper right of it, where it says "Checksum" would just say "calculating". MPLAB-X IDE still ran OK, so we resorted to using that to program the devices. We tried to uninstall 3.51 and reinstall. No luck. When 3.55 came out we tried installing that. No luck. We installed 3.51 on another computer and verified it was working as it used to on the first computer. Then we installed the Saleae analyzer. IPE Broken again. Installed 3.55 IPE still broken. Here's the interesing bit: IPE 3.40: Works perfectly fine. So, has anybody got any wild ideas as to what the heck is going on?
