嗨，@attila，非常感谢您的帮助！不幸的是，我仍然无法让它恢复运行。放弃并得到了新的？

嗨@attila，谢谢您的建议，我设法焊接了新的FTDI芯片。现在，该设备给了我一些响应，请参阅下面的错误消息。您是否有任何建议是否可以解决？我也不确定是否正确焊接了FTDI芯片 - 我很难将焊料交给焊料...再次感谢！

嗨@attila，感谢您指出相关帖子！我现在逐步遵循这一步骤，非常感谢您的进一步指导。我检查了铁矿，它们看起来不错（FB18，FB19均接近0欧姆，当拔下插头时，vbus在5V时，GND为0V）。然后，我检查了电压。VPLL，VCCD，VPHY均为5V，而不是3.3V，因此这可能是问题的一部分。VCCORE和VCCA为1.8V。现在，我可以做什么？我不太了解下面的USB电源控制图。具体来说，我没有在PCB板上找到IC21（ADM1177）。再次感谢你的帮助！

谢谢！抱歉，我最近刚刚在PC上使用了模拟发现2，直到它破裂为止...非常感谢您的建议！不幸的是，除非我可以修复或获得新建议，否则我无法测试您的建议？

Hi, I've been keeping my analog discovery 2 connected to my PC for forever, with also an external power supply (official one from Digilent) and things have been fine. I haven't used it recently, but just noticed today that it seems to be dead. There is an on-board LED which used to light up, but now is not doing anything. It doesn't get recognized by the computer (nothing in device manager). I don't see anything obviously burnt. Any suggestions on how I can figure out why it died, and if I can possibly repair it? Thank you!

也可能是与内核有关的问题吗？pi@raspberrypi：〜$ uname -r 5.4.79 -v7l+

嗨，我以前有模拟发现2与Raspberry Pi 4一起工作。但是，在我在Raspberry Pi上执行“ Sudo重新启动”之后，它今天停止工作，而模拟发现2则连接并运行。我检查了模拟发现在其他计算机上仍然可以正常工作（Windows 10，Ubuntu 20.04）。我在Raspberry Pi上尝试了不同的USB端口 /电缆，但没有运气。Raspberry Pi由原始电源提供动力，我现在仅连接模拟发现，因此不应该出现电源问题。我在Raspberry Pi上运行了“ USB驱动器”，看看是否有东西。但是，与不连接的模拟发现没有差异。无论如何，我还是列出了下面的输出，如果这可能会有所帮助。T：BUS = 01 LEV = 00 prnt = 00 port = 00 cnt = 00 dev＃= 1 spd = 480 mxch = 1 d：ver = 2.00 cls = 09（hub）sub = 00 prot = 01 mxps = 64＃cfgs = 64＃cfgs = 64＃cfgs =1 P：供应商= 1d6b prodid = 0002 rev = 05.04 S：制造商= Linux 5.4.79-V7L+ Xhci-hCD S：product = XHCI主机控制器S：SerialNumber = 0000：01：01：00.0 C：00.0.0 C：＃ifs = 1 CFG＃= 1 CFG＃= 1 CFG＃= 1 1 Atr=e0 MxPwr=0mA I: If#=0x0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=480 MxCh= 4 D: Ver= 2.10 Cls=09(hub ) Sub=00 Prot=01 MxPS=64 #Cfgs= 1 P: Vendor=2109 ProdID=3431 Rev=04.21 S: Product=USB2.0 Hub C: #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr=100mA I: If#=0x0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub T: Bus=02 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=5000 MxCh= 4 D: Ver= 3.00 Cls=09(hub ) Sub=00 Prot=03 MxPS= 9 #Cfgs= 1 P: Vendor=1d6b ProdID=0003 Rev=05.04 S: Manufacturer=Linux 5.4.79-v7l+ xhci-hcd S: Product=xHCI Host Controller S: SerialNumber=0000:01:00.0 C: #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr=0mA I: If#=0x0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub The Raspberry Pi USB ports seemingly are still working. I can read my HDD portable drive on it without any problem. I purged and reinstalled the following packages on my Pi, but still couldn't get connected. pi@raspberrypi:~ $ dpkg -l | grep digilent ii digilent.adept.runtime 2.21.2 armhf Digilent Adept Runtime ii digilent.adept.utilities 2.4.1 armhf Digilent Adept Utilities ii digilent.waveforms 3.14.3 armhf Digilent WaveForms I guess I should use the same version for the Waveforms and adept packages. However I can't find the same version number on the webpage. The earliest version of Waveforms that I can find is 3.0.16 while the most recent version of adept runtime is 2.21.2. So I just installed the latest version anyway... Any suggestions on how I can proceed? Thanks a lot for your help!
